| 1 | 离子渗氮AISI 420马氏体不锈钢耐蚀行为研究显示文摘采用不同温度对AISI 420马氏体不锈钢进行离子渗氮处理。借助光学显微镜和X射线衍射(XRD)技术分析了渗氮层的微观组织结构,利用显微硬度计测试了渗氮层的硬度分布,通过电化学极化曲线测试和盐雾腐蚀试验研究了离子渗氮AISI 420不锈钢在模拟工业环境中的腐蚀行为。结果表明:AISI 420不锈钢350℃低温离子渗氮层由ε-Fe3N和N过饱和固溶体αN相组成,其化学稳定性高,加之固溶Cr元素的联合作用,明显提高了AISI 420不锈钢基材的腐蚀抗力。AISI 420钢经450℃和550℃渗氮处理,渗氮层中的αN分解成了α相和CrN,造成基体贫Cr,降低了基材的耐蚀性能。马氏体不锈钢低温离子渗氮处理不仅可以提高表面硬度,而且可以获得良好的耐蚀性能。 | 奚运涛 刘道新 韩栋 韩增福 | 2007 | 材料热处理学报2007，28，5： | 18 |
| 2 | AISI316不锈钢腐蚀磨损交互作用的研究显示文摘采用电化学方法、微观形貌观察以及失重法分析研究了AISI316不锈钢和Al2O3陶瓷摩擦副在模拟海水中的腐蚀磨损行为,探讨了摩擦对不锈钢腐蚀行为的影响以及腐蚀磨损交互作用。结果表明,在本实验条件下摩擦作用显著增加了AISI316不锈钢的腐蚀倾向,其腐蚀率显著增加。纯磨损量占总腐蚀磨损量的76%~88%,材料的损失主要是由摩擦作用所引起,腐蚀磨损交互作用量占总腐蚀磨损量的12%-24%,腐蚀磨损交互作用是影响材料耐磨蚀性能的重要因素。 | 陈君 李全安 张清 王建章 阎逢元 | 2014 | 中国腐蚀与防护学报2014，34，5： | 15 |
| 3 | AISI 4340钢干滑动摩擦磨损特性研究显示文摘室温条件下,采用CFT-Ⅰ型多功能材料表面综合性能测试仪对AISI 4340钢进行了往复干摩擦磨损试验,研究了其摩擦磨损特性.采用扫描电子显微镜(SEM)和能谱仪(EDS)对磨痕和亚表层进行了观察和检测,分析了磨损表面微观形貌、亚表层塑性变形和碳氧元素含量演化.结果表明:磨损形式以磨粒磨损为主,并伴随轻微黏着磨损和剥落磨损;磨损表面分布着长度、宽度、深度不一的划痕以及鳞片状和颗粒状磨屑;磨损表面出现轻微氧化,磨屑呈现不同程度的碳富集和氧化;亚表层出现明显摩擦影响层,距表层越近,塑性变形越明显,晶界角逐渐汇聚于表面,在表面处趋于平行;往复运动导致塑性变形方向不一致,磨痕中部,塑性变形向某位置聚集. | 马红帅 梁国星 吕明 黄永贵 韩阳 | 2018 | 摩擦学学报2018，38，1： | 14 |
| 4 | AISI 316不锈钢和Ti6Al4V合金在海水环境中的腐蚀与腐蚀磨损行为(英文)显示文摘采用立式万能销盘腐蚀磨损试验机研究AISI 316不锈钢和Ti6Al4V合金在海水中与Al2O3陶瓷对磨时的腐蚀与腐蚀磨损行为,重点讨论腐蚀磨损之间的交互作用。结果表明,摩擦作用使得Ti6Al4V合金和316不锈钢的开路电位大幅下降,腐蚀磨损过程中的电流密度远高于静态腐蚀时的电流密度,摩擦明显促进了合金的腐蚀。两种合金在海水中的磨损量远大于在纯水中的磨损量,腐蚀促进了磨损,并且Ti6Al4V合金的耐磨性优于316不锈钢的耐磨性,腐蚀磨损之间的交互作用是材料损失的一个重要因素。本实验所用的摩擦装置为单向滑动的面面接触方式,这使得摩擦对腐蚀的促进作用在总磨损量中所占的比例很小。 | 陈君 张清 李全安 付三玲 王建章 | 2014 | Transactions of Nonferrous Metals Society of China2014，24，4： | 12 |
| 5 | Dynamic Recrystallization Behavior and Microstructure Evolution of AISI 304N Stainless Steel显示文摘Dynamic recrystallization of 304N stainless steel was investigated at deformation temperatures of 900-1 300℃ and strain rates of 0.01-10s-1 by a Gleeble-1500 thermo-mechanical simulator.And the microstructure evolutions of specimens with different deformation temperatures were observed by using a transmission electron microscope.Results indicated that compared with conventional AISI 304 austenitic stainless steel,304N stainless steel has higher deformation resistance force and deformation activation energy under similar conditions.In addition,the flow stress constitutive equation of 304N stainless steel was obtained by regression analysis of experimental stress-strain data,and the calculated values proposed by the mathematical model agree well with the experimental results. | WANG Chang-jun FENG Han ZHENG Wen-jie SONG Zhi-gang YONG Qi-long | 2013 | Journal of Iron and Steel Research(International)2013，20，10： | 11 |
| 6 | AISI 8620合金钢激光冲击强化层摩擦学特性显示文摘采用高能量激光束对AISI 8620合金钢表面进行冲击强化,利用CETR UMT-2摩擦磨损试验机对激光冲击试样表面进行磨损试验,并用扫描电子显微镜观察磨痕表面的形貌,研究激光冲击强化技术对AISI 8620合金钢耐磨损性能的影响。结果表明,激光冲击在AISI 8620合金钢表层形成残余压应力层,虽然残余压应力会降低氧化磨损和粘着磨损的抗性,但是会增加疲劳磨损的抗性,使AISI 8620合金钢试样的耐磨性提高1倍,多次冲击耐磨性能会更好。随着载荷的增加,激光冲击的AISI 8620合金钢试样的平均摩擦系数呈现先缓慢减小后缓慢增加的趋势。 | 钟俊伟 鲁金忠 罗开玉 杨超君 戴峰泽 钟金杉 王庆伟 齐晗 张磊 | 2012 | 中国激光2012，39，1： | 10 |
| 7 | Microstructure,Tensile and Impact Toughness Properties of Friction Stir Welded Mild Steel显示文摘Microstructure,tensile and impact toughness properties and fracture location of friction stir welded AISI 1018 mild steel were revealed.The AISI 1018 mild steel plates with thickness of 5 mm were friction stir welded by tungsten based alloy tool with tool rotational speed of 1000 r/min and welding speed of 50 mm/min.Tensile strength of stir zone is higher(8%)compared to that of the base metal.This may be due to the formation of finer grains in the weld nugget region under the stirring action of the rotating tool.The ductility and impact toughness of the joints are decreased compared to those of the base metal owing to the inclusion of tungsten particles in the weld region. | A K Lakshminarayanan V Balasubramanian M Salahuddin | 2010 | Journal of Iron and Steel Research(International)2010，17，10： | 10 |
| 8 | Influence of rare earths on eutectic carbides in AISI M2 high speed steel显示文摘The effect of rare earths on the morphology and microstructure of eutectic carbides in M2 high speed steel was studied. The results showed that rare earths promoted the formation of fishbone-like M6C eutectic carbides, compared to plate-like M2C carbides in ingots without modification. The formation of M6C was expected to be caused by rare earth inclusions which acted effectively as the substrate for nucleation of M6C carbides during solidification. M2C and M6C eutectic carbides exhibited different stability during heating. M2C eutectic carbides were much less stable than M6C carbides, and decomposed at high temperatures, favoring the spheroidization and refinement of carbides in high speed steels. | 周雪峰 殷晓燕 方峰 蒋建清 朱旺龙 | 2012 | Journal of Rare Earths2012，30，10： | 9 |
| 9 | Effect of cold rolling on the microstructural, magnetic, mechanical, and corrosion properties of AISI 316L austenitic stainless steel显示文摘This study has evaluated the effect of different levels of cold rolling(from 0 to 50%)on the microstructural,magnetic,and mechanical properties and the corrosion behavior of 316L austenitic stainless steel in Na Cl(1 mol/L)+H_2SO_4(0.5 mol/L)solution.Microstructural examinations using optical microscopy revealed the development of a morphological texture from coaxial to elongated grains during the cold-rolling process.Phase analysis carried out on the basis of X-ray diffraction confirmed the formation of the ferromagneticα′-martensite phase under the stresses applied during cold rolling.This finding is in agreement with magnetic measurements using a vibrating sample magnetometer.Mechanical properties determined by tensile and Vickers microhardness tests demonstrated an upward trend in the hardness-to-yield strength ratio with increasing cold-rolling percentage,representing a reduction in the material’s work-hardening ability.Uniform and localized corrosion parameters were estimated via potentiodynamic polarization corrosion tests and electrochemical impedance spectroscopy.In contrast to the uniform corrosion,wherein the corrosion current density increased with increasing cold-working degree because of the high density of microstructural defects,the passive potential range and breakdown potential increased by cold working,showing greater resistance to pit nucleation.Although pits were formed,the cold-rolled material repassivation tendency decreased because of the broader hysteresis anodic loop,as confirmed experimentally by observation of the microscopic features after electrochemical cyclic polarization evaluations. | S.Tanhaei Kh.Gheisari S.R.Alavi Zaree | 2018 | International Journal of Minerals,Metallurgy and Materials2018，25，6： | 9 |
| 10 | Nanoscale precipitates and comprehensive strengthening mechanism in AISI H13 steel显示文摘The effects of heat treatment on the precipitates and strengthening mechanism in AISI H13 steel were investigated. The results showed that the presence of nanoscale precipitates favorably affected grain refinement and improved the yield strength. The volume fraction of precipitates increased from 1.05% to 2.85% during tempering, whereas the average precipitate size first decreased then increased during tempering. Contributions to the yield strength arising from the various mechanisms were calculated quantificationally, and the results demonstrated that grain refinement and dislocation density most strongly influenced the yield strength. In addition, under the interaction of average size and volume fraction, precipitates' contribution to the yield strength ranged from 247.9 to 378.5 MPa. Finally, a root-mean-square summation law of σ = σ_g + σ_s +(σ_d^2 + σ_p^2)^(1/2), where σ_g, σ_s, σ_d, and σ_p represent the contributions of fine-grain strengthening, solid-solution strengthening, dislocation strengthening, and precipitation strengthening, respectively, was confirmed as the most applicable for AISI H13 steel, which indicates a strong link between precipitates and dislocations in AISI H13 steel. | Wen-wen Mao An-gang Ning Han-jie Guo | 2016 | International Journal of Minerals,Metallurgy and Materials2016，23，9： | 9 |
| 11 | 以银为中间层扩散连接Ti-6Al-4V和304不锈钢的工艺窗口(英文)显示文摘由于钛合金具有高的化学活性,很难采用传统焊接技术进行连接。在钛合金和不锈钢熔焊过程中,钛容易与空气中的氮和氧反应形成脆性中间化合物,降低焊接接头的力学性能。因此,宜采用扩散连接钛合金。以银为中间层,研究扩散连接Ti-6Al-4V和AISI304不锈钢的工艺参数。通过搭接剪切实验和显微组织分析对接头质量进行评价。通过实验结果得到扩散连接的工艺窗口,为获得无缺陷接头工艺参数提供参考。在750-800°C时可以成功进行扩散连接。在5 MPa和90 min条件下焊接接头可获得最大搭接剪切强度。 | M.BALASUBRAMANIAN | 2015 | Transactions of Nonferrous Metals Society of China2015，25，9： | 9 |

| 13 | Evaluation of Microstructure and Mechanical Properties of Laser Beam Welded AISI 409M Grade Ferritic Stainless Steel显示文摘The microstructure analysis and mechanical properties evaluation of laser beam welded AISI 409M ferritic stainless steel joints are investigated.Single pass autogeneous welds free of volumetric defects were produced at a welding speed of 3 000 mm/min.The joints were subjected to optical microscope,scanning electron fractographe,microhardness,transverse and longitudinal tensile,bend and charpy impact toughness testing.The coarse ferrite grains in the base metal were changed into dendritic grains as a result of rapid solidification of laser beam welds.Tensile testing indicates overmatching of the weld metal is relative to the base metal.The joints also exhibited acceptable impact toughness and bend strength properties. | A K Lakshminarayanan V Balasubramanian | 2012 | Journal of Iron and Steel Research(International)2012，19，1： | 9 |
| 14 | Wear and corrosion resistance of laser-cladded Fe-based composite coatings on AISI 4130 steel显示文摘The wear and corrosion resistance of Fe_(72.2)Cr_(16.8)Ni_(7.3)Mo_(1.6)Mn_(0.7)C_(0.2)Si_(1.2) and Fe_(77.3)Cr_(15.8)Ni_(3.9)Mo_(1.1)Mn_(0.5)C_(0.2)Si_(1.2) coatings laser-cladded on AISI 4130 steel were studied.The coatings possess excellent wear and corrosion resistance despite the absence of expensive yttrium,tungsten,and cobalt and very little molybdenum.The microstructure mainly consists of dendrites and eutectic phases,such as duplex(γ+α)-Fe and the Fe–Cr(Ni)solid solution,confirmed via energy dispersive spectrometry and X-ray diffraction.The cladded Fe-based coatings have lower coefficients of friction,and narrower and shallower wear tracks than the substrate without the cladding,and the main wear mechanism is mild abrasive wear.Electrochemical test results suggest that the soft Fe_(72.2)Cr_(16.8)Ni_(7.3)Mo_(1.6)Mn_(0.7)C_(0.2)Si_(1.2) coating with high Cr and Ni concentrations has high passivation resistance,low corrosion current,and positive corrosion potential,providing a better protective barrier layer to the AISI 4130 steel against corrosion. | Li Fan Hai-yan Chen Yao-hua Dong Li-hua Dong Yan-sheng Yin | 2018 | International Journal of Minerals,Metallurgy and Materials2018，25，6： | 9 |
| 15 | Effect of Heat Treatment on Microstructure of Modified Cast AISI D3 Cold Work Tool Steel显示文摘The effects of heat treatment on the microstructure of modified cast high chromium high carbon AISI D3 steel were studied.The modified AISI D3 steel was developed by replacing part of chromium with niobium and titanium,in which chromium carbide was partially replaced with MC carbides.The cast samples produced by investment casting were heat treated under different conditions.The microstructures of the samples were studied by optical microscope and scanning electron microscope equipped with EDS analyzer.To determine the optimized homogenizing process,the effects of homogenizing treatment on the microstructure and the morphology of carbides were also studied.The results show that the MC carbides are not changed in shape and amounts during high temperature homogenizing,whereas the M3C carbides are reduced in amount and become semiglobular in shape,and the homogeneity of microstructure is improved. | Shahram Kheirandish Hasan Saghafian Jalal Hedjazi Mohammad Momeni | 2010 | Journal of Iron and Steel Research(International)2010，17，9： | 8 |
| 16 | Antibacterial properties and corrosion resistance of AISI 420 stainless steels implanted by silver and copper ions显示文摘Silver or copper ions are often chosen as antibacterial agents. But a few reports are concerned with these two antibacterial agents for preparation of antibacterial stainless steel (SS). The antibacterial properties and corrosion resistance of AISI 420 stainless steel implanted by silver and copper ions were investigated. Due to the cooperative antibacterial effect of silver and copper ions, the Ag/Cu implanted SS showed excellent antibacterial activities against both Gram-negative Escherichia coli (E. coli) and Gram-positive Staphylococcus aureus (S. aureus) at a total implantation dose of 2×1017 ions/cm2. Electrochemical polarization curves revealed that the corrosion resistance of Ag/Cu implanted SS was slightly enhanced as compared with that of un-implanted SS. The implanted layer was characterized by X-ray photoelec-tron spectroscopy (XPS). Core level XPS spectra indicate that the implanted silver and copper ions exist in metallic state in the implanted layer. | Hong-wei Ni Han-shuang Zhang Rong-sheng Chen Wei-ting Zhan Kai-fu Huo Zhen-yu Zuo | 2012 | International Journal of Minerals,Metallurgy and Materials2012，19，4： | 8 |

| 18 | Friction welding of AA6061 to AISI 4340 using silver interlayer显示文摘The present work pertains to the study on joining of AA6061 and AISI 4340 through continuous drive friction welding. The welds were evaluated by metallographic examination, X-ray diffraction, electron probe microanalysis, tensile test and microhardness. The study reveals that the presence of an intermetallic compound layer at the bonded interface exhibits poor tensile strength and elongation. Mg in AA6061 near to the interface is found to be favourable for the formation and growth of Fe2Al5 intermetallics. Introduction of silver as an interlayer through electroplating on AISI 4340 resulted in accumulation of Si at weld interface, replacing Mg at AA6061 side, thereby reducing the width of intermetallic compound layer and correspondingly increasing the tensile strength. Presence of silver at the interface results in partial replacement of Fe-Al based intermetallic compounds with Ag-Al based compounds. The presence of these intermetallics was confirmed by X-ray diffraction technique. Since Ag-Al phases are ductile in nature, tensile strength is not deteriorated and the silicon segregation at weld interface on AA6061 in the joints with silver interlayer acts as diffusion barrier for Fe and further avoids formation of Fe-Al based intermetallics. A maximum tensile strength of 240 MPa along with 4.9% elongation was obtained for the silver interlayer dissimilar metal welds. The observed trends in tensile properties and hardness were explained in relation to the microstructure. | SURESH D.MESHRAM G.MADHUSUDHAN REDDY | 2015 | Defence Technology(防务技术)2015，11，3： | 7 |
| 19 | Corrosion of AISI 4130 Steel Alloy under Hydrodynamic Condition in Ethylene Glycol+Water+NO_2^- Solution显示文摘The electrochemical behavior of steel alloy in ethylene glycol-water mixture at different solution rotating speeds was investigated by polarization curves and AC impedance measurements (EIS). The results obtained showed that corrosion rate was not changed significantly at different rotating speeds and was decreased with increasing ethylene glycol concentration. The effect of nitrite as an inhibitor was studied and high inhibition efficiency was obtained. It was found that surface passivation occurred in the presence of inhibitor. The inhibiting effect of the nitrite was explained on the basis of the competitive adsorption between the inorganic anions and the aggressive Cl- ions and the adsorption isotherm basically obeys the Flory-Huggins adsorption isotherm. Thermodynamic parameters for steel corrosion and inhibitor adsorption were determined, which revealed that the adsorption process is spontaneous. | I.Danaee M.Niknejad Khomami A.A.Attar | 2013 | Journal of Materials Science & Technology2013，29，1： | 7 |
| 20 | Hot compression deformation behavior of AISI 321 austenitic stainless steel显示文摘The hot compression behavior of AISI 321 austenitic stainless steel was studied at the temperatures of 950- 1100 C and the strain rates of 0.01-1s1 using a Baehr DIL-805 deformation dilatometer. The hot deformation equations and the relationship between hot deformation parameters were obtained. It is found that strain rate and deformation temperature significantly influence the flow stress behavior of the steel. The work hardening rate and the peak value of flow stress increase with the decrease of deformation temperature and the increase of strain rate. In addition, the activation energy of deformation (Q) is calculated as 433.343kJ/mol. The microstructural evolution during deformation indicates that, at the temperature of 950C and the strain rate of 0.01s1 , small circle-like precipitates form along grain boundaries; but at the temperatures above 950C, the dissolution of such precipitates occurs. Energy-dispersive X-ray analyses indicate that the precipitates are complex carbides of Cr, Fe, Mn, Ni, and Ti. | Mehdi Haj Hojjatollah Mansouri Reza Vafaei Golam Reza Ebrahimi Ali Kanani | 2013 | International Journal of Minerals,Metallurgy and Materials2013，20，6： | 7 |
