| 1 | One-step Crystallization Kinetic Parameters of the Glass-ceramics Prepared from Stainless Steel Slag and Pickling Sludge显示文摘One-step crystallization is one of the most energy conserving methods for glass-ceramics preparation.However,only a few kinetics studies focused on the glass-ceramics prepared by the one-step crystallization.The onestep crystallization kinetic parameters were studied using differential scanning calorimetry.The activation energy(Ea)and the Avrami parameter(n)were calculated as 152.79kJ·mol-1 and 4.39,respectively.These parameters indicate that continuous nucleation and three-dimensional crystal growth are the dominating mechanisms in the one-step crystallization process of the parent glass.The properties of the obtained glass-ceramics can be compared to the glass-ceramics prepared by the two-stage heat treatment and sintering method.This crystallization kinetics research can be used to evaluate the one-step crystallization potential of a parent glass. | Shen-gen ZHANG Jian YANG Bo LIU De-an PAN Chun-li WU Alex A.VOLINSKY | 2016 | Journal of Iron and Steel Research(International)2016，23，3： | 7 |
| 2 | Treatment method of hazardous pickling sludge by reusing as glass–ceramics nucleation agent显示文摘Heavy metal containing pickling sludge(PS) is one of the by-products of the stainless-steel-making industry,which has been considered hazardous due to contained chromium and nickel.Traditional methods of PS disposing are landfill and cement solidification.This research is aimed at disposing PS by solidification/stabilization and reusing it as a nucleation agent of glass–ceramics.The crystallization behavior and the properties of a glass in the CaO–MgO–SiO_2–Al_2O_3 system were studied by considering PS as the nucleation agent.Experimental results confirm that introducing 14 wt% PS as the nucleation agent of glass–ceramics can decrease crystallization temperature by 110.8 °C,refine the grain size by forming isometric crystals with size of 2 lm,enhance Vickers hardness by 2690 MPa and decrease water absorption from(1.21 ± 0.10) wt% to(0.04 ± 0.01) wt%.Therefore,it is reasonable to conclude that PS can be utilized as a nucleation agent to improve the crystallization and mechanical properties of the glass–ceramics.The testing results of US EPA toxicity characteristic leaching procedure(TCLP)confirm the safety of this reusing method. | Jian Yang Shen-Gen Zhang De-An Pan Bo Liu Chun-Li Wu Alex A.Volinsky | 2016 | Rare Metals2016，35，3： | 6 |
| 3 | Spheroidization of molybdenum powder by radio frequency thermal plasma显示文摘To control the morphology and particle size of dense spherical molybdenum powder prepared by radio frequency(RF) plasma from irregular molybdenum powder as a precursor, plasma process parameters were optimized in this paper. The effects of the carrier gas flow rate and molybdenum powder feeding rate on the shape and size of the final products were studied. The molybdenum powder morphology was examined using high-resolution scanning electron microscopy. The powder phases were analyzed by X-ray diffraction. The tap density and apparent density of the molybdenum powder were investigated using a Hall flow meter and a Scott volumeter. The optimal process parameters for the spherical molybdenum powder preparation are 50 g/min powder feeding rate and 0.6 m3/h carrier gas rate. In addition, pure spherical molybdenum powder can be obtained from irregular powder, and the tap density is enhanced after plasma processing. The average size is reduced from 72 to 62 μm, and the tap density is increased from 2.7 to 6.2 g/cm3. Therefore, RF plasma is a promising method for the preparation of high-density and high-purity spherical powders. | Xiao-ping Liu Kuai-she Wang Ping Hu Qiang Chen Alex A.Volinsky | 2015 | International Journal of Minerals,Metallurgy and Materials2015，22，11： | 6 |
| 4 | Recent advances and perspective in metal coordination materialsbased electrode materials for potassium-ion batteries显示文摘Recently,to ameliorate the forthcoming energy crisis,sustainable energy conversion and storage devices have been extensively investigated.Potassium-ion batteries(KIBs)have aroused widespread attention in these very active research applications due to their earth abundance and similar low redox potential compared to Li-ion batteries(LIBs).It is critical to develop electrode materials with large ion diffusion channels and robust structures for long cycling performance in KIBs.Metal coordination materials,including metal-organic frameworks,Prussian blue,and Prussian blue analogue,as well as their composites and derivatives,are known as promising materials for high-performance KIBs due to their open frameworks,large interstitial voids,functionality and tailorability.In this review,we give an overview of the recent advances on the application of metal coordination materials in KIBs.In addition,the methods to enhance their K-ion storage properties are summarized and discussed,such as morphology engineering,doping,as well as compositing with other materials.Ultimately,some prospects for future research of metal coordination materials for KIBs are also proposed. | Fei Wang Yong Liu Hui-Jie Wei Teng-Fei Li Xun-Hui Xiong Shi-Zhong Wei Feng-Zhang Ren Alex A.Volinsky | 2021 | Rare Metals2021，40，2： | 5 |

| 6 | Recycle of valuable products from oily cold rolling mill sludge显示文摘Oily cold rolling mill(CRM)sludge contains lots of iron and alloying elements along with plenty of hazardous organic components,which makes it as an attractive secondary source and an environmental contaminant at the same time.The compound methods of'vacuum distillation+oxidizing roasting'and'vacuum distillation+hydrogen reduction'were employed for the recycle of oily cold rolling mill sludge.First,the sludge was dynamically vacuum distilled in a rotating furnace at 50 r/min and 600 C for 3 h,which removed almost hazardous organic components,obtaining 89.2wt%ferrous resultant.Then,high purity ferric oxide powders(99.2wt%)and reduced iron powders(98.9wt%)were obtained when the distillation residues were oxidized and reduced,respectively.The distillation oil can be used for fuel or chemical feedstock,and the distillation gases can be collected and reused as a fuel. | Bo Liu Shen-gen Zhang Jian-jun Tian De-an Pan Yang Liu Alex A.Volinsky | 2013 | International Journal of Minerals,Metallurgy and Materials2013，20，10： | 5 |
| 7 | Initial formation of corrosion products on pure zinc in simulated body fluid显示文摘Zinc was recently suggested to be a potential candidate material for degradable coronary artery stent.The corrosion behavior of pure zinc exposed to r-SBF up to 336 h was investigated by electrochemical measurements and immersion tests. The morphology and chemical composites of the corrosion products were investigated by scanning electron microscope, grazing-incidence X-ray diffraction, X-ray photoelectron spectroscopy and Fourier transform infrared spectrometer. The results demonstrate that the initial corrosion products on the pure zinc mainly consist of zinc oxide/hydroxide and zinc/calcium phosphate compounds. The pure Zn encounters uniform corrosion with an estimated corrosion rate of 0.02-0.07 mmy^(-1) during the immersion, which suggests the suitability of pure Zn for biomedical applications. | Lijun Liu Yao Meng Chaofang Dong Yu Yan Alex A.Volinsky Lu-Ning Wang | 2018 | Journal of Materials Science & Technology2018，34，12： | 4 |
| 8 | Characterization of the Hot Deformation Behavior of Cu–Cr–Zr Alloy by Processing Maps显示文摘Hot deformation behavior of the Cu–Cr–Zr alloy was investigated using hot compressive tests in the temperature range of 650–850 °C and strain rate range of 0.001–10 s-1. The constitutive equation of the alloy based on the hyperbolic-sine equation was established to characterize the flow stress as a function of strain rate and deformation temperature. The critical conditions for the occurrence of dynamic recrystallization were determined based on the alloy strain hardening rate curves. Based on the dynamic material model, the processing maps at the strains of 0.3, 0.4 and 0.5were obtained. When the true strain was 0.5, greater power dissipation efficiency was observed at 800–850 °C and under0.001–0.1 s-1, with the peak efficiency of 47%. The evolution of DRX microstructure strongly depends on the deformation temperature and the strain rate. Based on the processing maps and microstructure evolution, the optimal hot working conditions for the Cu–Cr–Zr alloy are in the temperature range of 800–850 °C and the strain rate range of 0.001–0.1 s-1. | Yi Zhang Hui-Li Sun Alex A.Volinsky Bao-Hong Tian Zhe Chai Ping Liu Yong Liu | 2016 | Acta Metallurgica Sinica(English Letters)2016，29，5： | 3 |
| 9 | Fabrication and characterization of anodic oxide nanotubes on TiNb alloys显示文摘Titanium and its alloys have been extensively used as implant materials owing to their high specific strength, good biocompatibility and excellent corrosion resistance. Oxide nanotubular array layer can be formed on Ti alloy surface by electrochemical anodization treatment. In this work, the morphology of nanotubes formed on Ti–Nb alloys(Nb content of 5 wt%, 10 wt%, 20 wt%, 30 wt% and40 wt%) was investigated using an electrolyte containing ethylene glycol and NH_4 F. Oxide layers consisting of highly ordered nanotubes with a range of diameters(approximately40–55 nm for the inner diameter and 100–120 nm for the outer diameter) and lengths(approximately 10–20 lm) can be formed on alloys in the Ti–x Nb system, independent on the Nb content. The nanotubes formed on the Ti–Nb alloy surface were transformed from the anatase to rutile structure of titanium oxide. The oxide nanotubular surface is highly hydrophilic compared with the intact Ti Nb foil. The surface wettability varies with the nanotube diameter. As the nanotube diameter increases while the nanotube layer thickness remains constant, the capillary wetting of the nanotube surface decreases and the surface becomes less hydrophilic.Annealing changes the nanotubular surface wettability further and establishes less hydrophilic surface conditions due to the removal of hydroxyl groups and residue fluoridecontaining species. It is believed that the surface wettability is changed due to the decreasing content of hydroxyl groups in ambient atmosphere. This work can provide guidelines for improving structural and environmental conditions responsible for changing surface wettability of Ti Nb surfaces for biomedical applications. | Ming Jin Xin Lu Yi Qiao Lu-Ning Wang Alex A.Volinsky | 2016 | Rare Metals2016，35，2： | 3 |
| 10 | Microstructure Evolution and Microhardness of Ultrafine-grained High Carbon Steel during Multiple Laser Shock Processing显示文摘Surface microstructure and microhardness of(ferrite+cementite)microduplex structure of the ultrafinegrained high carbon steel after laser shock processing(LSP)with different impact times were investigated by means of scanning electron microscopy(SEM),transmission electron microscopy(TEM),X-ray diffraction(XRD)and microhardness measurements.Equiaxed ferrite grains were refined from 400 to 150nm,and the cementite lamellae were fully spheroidized,with a decrease of the particle diameter from 150 to 100nm as the impact times increased.The cementite dissolution was enhanced significantly.Correspondingly,the lattice parameter ofα-Fe and microhardness increased with the impact times. | Yi XIONG Tian-tian HE Feng-zhang REN Peng-yan LI Lu-fei CHEN Alex A.VOLINSKY | 2015 | Journal of Iron and Steel Research(International)2015，22，1： | 2 |
| 11 | Effects of laser pulse energy on surface microstructure and mechanical properties of high carbon steel显示文摘Surface microstructure and mechanical properties of pearlitic Fe–0.8%C(mass fraction) steel after laser shock processing(LSP) with different laser pulse energies were investigated by scanning electron microscopy(SEM),transmission electron microscopy(TEM),X-ray diffraction(XRD) and microhardness measurements.After LSP,the cementite lamellae were bent,kinked and broken into particles.Fragmentation and dissolution of the cementite lamellae were enhanced by increasing the laser pulse energy.Due to the dissolution of carbon atoms in the ferritic matrix,the lattice parameter of α-Fe increased.The grain size of the surface ferrite was refined,and the microstructure changed from lamellae to ultrafine micro-duplex structure(ferrite(α)+cementite(θ)) with higher laser pulse energy,accompanied by the residual stress and microhardness increase. | 熊毅 贺甜甜 李鹏燕 陈路飞 任凤章 Alex A.Volinsky | 2015 | Journal of Central South University2015，22，12： | 2 |
| 12 | Mechanism of CeMgAl_(11)O_(19):Tb^(3+) alkaline fusion with sodium hydroxide显示文摘Comprehensive CeMgAl11O19:Tb3+(CTMA)disintegration via alkaline fusion was discussed. The rare earth(RE) elements in CTMA were dissolved by HCl completely after alkaline fusion. Relationships between the alkaline fusion temperature and various properties of the compounds were examined by various techniques to elucidate their roles in the expected CTMA disintegration.X-ray diffraction(XRD) analysis indicates the phase transformation sequence. A scientific hypothesis of crystal structure disintegration presents that sodium ions substitute for the europium and barium ions in the mirror plane and magnesium ions in the spinel block successively, resulting in that more oxygen vacancies and interstitial sodium ions appear. The unit cell [P63/mmc(194)] breaks from the mirror plane. Then it is decomposed into Na Al O2, and magnesium, cerium, and terbium ions combine with free OH-into Mg O, Tb2O3 and CeO2;Tb2O3 and CeO2 change into Ce0.6Tb0.4O2-x. In the end, the rare earth oxide is recycled easily by the acidolysis. The mechanism provides fundamental basis for recycling of REEs from waste phosphors. | Hu Liu Shen-Gen Zhang De-An Pan Yi-Fan Liu Bo Liu Jian-Jun Tian Alex A.Volinsky | 2015 | Rare Metals2015，34，3： | 1 |
| 13 | Properties and precipitates of the high strength and electrical conductivity Cu-Ni-Co-Si-Cr alloy显示文摘In this paper,a novel Cu-1.5 Ni-1.1 Co-0.6 Si-0.1 Cr(wt.%)alloy with high strength and electrical conductivity was designed.After aging,excellent properties of 857±12 MPa yield strength,300±8 HV microhardness,42.8±2.5%IACS conductivity,and 7±0.5%elongation were obtained.According to the atomic structure,part of Ni atoms in Ni_(2)Si can be replaced by Co atoms to form nano-precipitates(Ni,Co)_(2)Si.The alloy’s high strength and conductivity are mainly attributed to the fine and uniformly distributed(Ni,Co)_(2)Si and Cr nano precipitates.The alloy strength was also enhanced by twins,dislocations,and grain refining strengthening.Based on the investigations of deformation microstructure and the orientation relationship between the(Ni,Co)_(2)Si precipitates and the Cu matrix,the main reason for elongation increase is attributed to the formation of deformation twins and the small lattice mismatch strain at the coherent interfaces of precipitates and the Cu matrix. | Yijie Ban Yongfeng Geng Jinrui Hou Yi Zhang Meng Zhou Yanlin Jia Baohong Tiana Yong Liua Xu Li Alex A.Volinsky | 2021 | Journal of Materials Science & Technology2021，，34： | 1 |
| 14 | Current-voltage characteristics of lead zirconate titanate/nickel bilayered hollow cylindrical magnetoelectric composites显示文摘Current-voltage measurements obtained from lead zirconate titanate/nickel bilayered hollow cylindrical magne-toelectric composite showed that a sinusoidal current applied to the copper coil wrapped around the hollow cylinder circumference induces voltage across the lead zirconate titanate layer thickness. The current-voltage coefficient and the maximum induced voltage in lead zirconate titanate at 1 kHz and resonance (60.1 kHz) frequencies increased linearly with the number of the coil turns and the applied current. The resonance frequency corresponds to the electromechanical resonance frequency. The current-voltage coefficient can be significantly improved by optimizing the magnetoelectric structure geometry and/or increasing the number of coil turns. Hollow cylindrical lead zirconate titanate/nickel struc-tures can be potentially used as current sensors. | 潘德安 张深根 田建军 孙俊赛 Alex A.Volinsky 乔利杰 | 2010 | Chinese Physics B2010，19，2： | 1 |
| 15 | Review of the fatigue behavior of hard coating–ductile substrate systems显示文摘With the wide application of coating materials in aerospace and other fields, their safety under fatigue conditions in service is important.However, research on the fatigue properties of ceramic hard coatings started late, and a unified standard is yet to be established to evaluate the fatigue life of hard coating–ductile substrate systems.Studies also present different opinions on whether coatings can improve or reduce the fatigue life of substrates.In this paper, the influence of the properties of ceramic coatings on fatigue performance is reviewed, and the effects of coating on the mechanism of fatigue crack initiation in substrates are discussed, aiming to help readers understand the fatigue behavior of hard coating–ductile substrate systems. | Yan-yun Bai Jin Gao Tao Guo Ke-wei Gao Alex A.Volinsky Xiao-lu Pang | 2021 | International Journal of Minerals,Metallurgy and Materials2021，28，1： | 1 |
| 16 | Effect of TiO_2 on Crystallization,Microstructure and Mechanical Properties of Glass-ceramics显示文摘The effect of TiO_2 addition to the stainless steel slag glass-ceramics was studied.Different mass percentages of TiO_2 were added to four samples of the parent glass made from stainless steel slag and cullet.The temperatures of nucleation and crystallization were determined by differential scanning calorimetry(DSC).According to Xray diffraction(XRD) and scanning electron microscopy(SEM) analysis,adding TiO_2 refined grains and restricted the formation of the akermanite phase by capturing Ca^(2+) to form the perovskite phase.Diopside was the main crystal phase of the glass-ceramics.The bending strength and Vickers hardness increased with the addition of TiO_2.The optimal amount of TiO_2 was 7 mass%,and the highest bending strength and Vickers hardness were 144.6 MPa and6.26 GPa,respectively. | Jian YANG Shen-gen ZHANG Bo LIU De-an PAN Chun-li WU Alex A.VOLINSKY | 2015 | Journal of Iron and Steel Research(International)2015，22，12： | 0 |
| 17 | Surface effects on static bending of nanowires based on non-local elasticity theory显示文摘The surface elasticity and non-local elasticity effects on the elastic behavior of statically bent nanowires are investigated in the present investigation. Explicit solutions are presented to evaluate the surface stress and non-local elasticity effects with various boundary conditions.Compared with the classical Euler beam, a nanowire with surface stress and/or non-local elasticity can be either stiffer or less stiff, depending on the boundary conditions. The concept of surface non-local elasticity was proposed and its physical interpretation discussed to explain the combined effect of surface elasticity and non-local elasticity. The effect of the nanowire size on its elastic bending behavior was investigated. The results obtained herein are helpful to characterize mechanical properties of nanowires and aid nanowire-based devices design. | Quan Wu Alex A.Volinsky Lijie Qiao Yanjing Su | 2015 | Progress in Natural Science:Materials International2015，25，5： | 0 |
| 18 | Height-related magnetoelectric performance of PZT/Ni layered composites显示文摘The effect of height on performance of the PZT/Ni cylindrical bilayered magnetoelectric(ME) composites was studied in situ in this paper.Multiple resonant peaks appear between 1 and 300 kHz frequency for cylinders of different heights.The first resonance frequency does not change with the cylinder height decreasing,but the second and the third resonant frequencies increase.The first three resonant modes are attributed to the cylinder radial,first-order height resonance,and second-order height resonance,respectively.The appropriate size and resonance frequency were chosen to obtain the highest ME voltage coefficient when designing cylindrical bilayered magnetoelectric devices.This article provides reference to design cylindrical magnetoelectric devices. | Zhi-Jun Zuo De-An Pan Li-Jun Wang Jian-Jun Tian Shen-Gen Zhang Li-Jie Qiao Alex A.Volinsky | 2017 | Rare Metals2017，36，7： | 0 |
| 19 | Microstructure and Hardness of Laser Shocked Ultra-fine-grained Aluminum显示文摘Ultra-fine-grained commercial purity aluminum was produced by severe cold rolling, annealing and then strain- ing at ultra-high rate by a single pass laser shock. Resulted microstructure was investigated by transmission electron microscopy. Microhardness of annealed 0.6 μm ultra-fine grained aluminum increased by 67% from 24 to 40 HV. Many 0.3 μm sub-grains appeared at the shock wave center after a single pass laser shock, while high density dislocation networks were observed in some grains at the shock wave edges. Accordingly, microhardness at the impact center increased by 37.5% from 40 to 55 HV. From the impact center to the edge, microhardness decreased by 22% from 55 to 45 HV. | Tiantian He Yi Xiong Zhiqiang Guo Lingfeng Zhang Fengzhang Ren Alex A.Volinsky | 2011 | Journal of Materials Science & Technology2011，27，9： | 0 |
| 20 | Nd_2Fe_(17) nanograins effect on the coercivity of HDDR NdFeB magnets with low boron content显示文摘Relationships between the coercivity of hydrogenation disproportionation desorption recombination(HDDR) Nd12.5Fe81.5-xCo6Bx bonded magnets and boron content were investigated.Nd2Fe17 phase with planar magnetic anisotropy is present in the microstructure when x= 4at%-5.88at%,which does not reduce the coercivity of the bonded magnets.High-resolution transmission electron microscopy(TEM) images show that Nd2Fe17 phase exists in the form of nanocrystals in the Nd2Fe14B matrix.There is an exchange-coupling interaction between the two phases so that the coercivity of HDDR Nd12.5Fe81.5-xCo6Bx bonded magnets is hardly reduced with a decrease in boron content. | Ai-zhi Sun Shen Wu Wen-huan Xu Jin Wang Qian Zhang Fu-qiang Zhai Alex A.Volinsky | 2012 | International Journal of Minerals,Metallurgy and Materials2012，19，3： | 0 |
