| 1 | Effects of deformation twinning on the mechanical properties of biodegradable Zn-Mg alloys显示文摘To satisfy the property requirements for biodegradable medical implants,Zn alloyed with low levels of Mg(≤0.8 wt%)has attracted increased research interest.In the present study,deformation twinning was observed in tensile tests and twinning appears to have an adverse impact on ductility.The profuse twinning in the as-cast Zn-Mg alloys accelerated crack growth in tension due to twinning impingement which caused local stress concentrations and initiates cracking.As-rolled Zn-Mg alloys have better ductility than their as-cast counterparts due to the inhibition of twinning by the refined Mg2Zn11 intermetallic phase and the finer grain size. | Shiyang Liu Damon Kent Nghiem Doan Matthew Dargusch Gui Wang | 2019 | Bioactive Materials2019，4，1： | 5 |

| 3 | Biodegradable Zn–3Cu and Zn–3Cu–0.2Ti alloys with ultrahigh ductility and antibacterial ability for orthopedic applications显示文摘Zinc(Zn) and its alloys have been proposed as biodegradable implant materials due to their unique combination of biodegradability, biocompatibility, and biofunctionality. However, the insufficient mechanical properties of pure Zn greatly limit its clinical application. Here, we report on the microstructure, mechanical properties, friction and wear behavior, corrosion and degradation properties, hemocompatibility, and cytocompatibility of Zn–3 Cu and Zn–3 Cu–0.2 Ti alloys under three different conditions of as-cast(AC),hot-rolling(HR), and hot-rolling plus cold-rolling(HR + CR). The HR + CR Zn–3 Cu–0.2 Ti exhibited the best set of comprehensive properties among all the alloy samples, with yield strength of 211.0 MPa, ultimate strength of 271.1 MPa, and elongation of 72.1 %. Immersion tests of the Zn–3 Cu and Zn–3 Cu–0.2 Ti alloys in Hanks’ solution for 3 months indicated that the AC samples showed the lowest degradation rate,followed by the HR samples, and then the HR + CR samples, while the HR + CR Zn–3 Cu exhibited the highest degradation rate of 23.9 m/a. Friction and wear testing of the Zn–3 Cu and Zn–3 Cu–0.2 Ti alloys in Hanks’ solution indicated that the AC samples showed the highest wear resistance, followed by the HR samples, and then the HR + CR samples, while the AC Zn–3 Cu–0.2 Ti showed the highest wear resistance.The diluted extracts of HR + CR Zn–3 Cu and Zn–3 Cu–0.2 Ti at a concentration of ≤25 % exhibited noncytotoxicity. Furthermore, both the HR + CR Zn–3 Cu and Zn–3 Cu–0.2 Ti exhibited effective antibacterial properties against S. aureus. | Jixing Lin Xian Tong Kun Wang Zimu Shi Yuncang Li Matthew Dargusch Cuie Wen | 2021 | Journal of Materials Science & Technology2021，，9： | 3 |
| 4 | What activates the Mg surface——A comparison of Mg dissolution mechanisms显示文摘Several mechanisms have been proposed to interpret the widely reported phenomenon of Mg corrosion that the hydrogen evolution rate increases with increasing anodic potential or anodic current density. This paper critically analyzed the two main mechanisms,(1) 'the incomplete film univalent Mg+ion mechanism' and(2) 'the enhanced catalytic activity mechanism', aiming to clarify the current understanding of the Mg corrosion mechanism and to provide a profound insight into the Mg characteristic electrochemical behavior, anodic polarization accelerating both hydrogen evolution and Mg dissolution. It is expected that the deepened fundamental understanding from this comprehensive mechanistic review will provide a basis of practical applications for Mg alloys and open up a new way to the control of corrosion of Mg alloys in practice. | Jufeng Huang Guang-Ling Song Andrej Atrens Matthew Dargusch | 2020 | Journal of Materials Science & Technology2020，54，22： | 3 |

| 6 | Challenges in laser-assisted milling of titanium alloys显示文摘Several detailed studies have comprehensively investigated the benefits and limitations of laser-assisted machining(LAM)of titanium alloys.These studies have highlighted the positive impact of the application of laser preheating on reducing cutting forces and improving productivity but have also identified the detrimental effect of LAM on tool life.This paper seeks to evaluate a series of the most common cutting tools with different coating types used in the machining of titanium alloys to identify whether coating type has a dramatic effect on the dominant tool wear mechanisms active during the process.The findings provide a clear illustration that the challenges facing the application of LAM are associated with the development of new types of cutting tools which are not subjected to the diffusion-controlled wear processes that dominate the performance of current cutting tools. | Matthew S Dargusch Tharmalingam Sivarupan Michael Bermingham Rizwan Abdul Rahman Rashid Suresh Palanisamy Shoujin Sun | 2021 | International Journal of Extreme Manufacturing2021，3，1： | 3 |
| 7 | 建立一个生物腐蚀研究的标准化方法:与体内腐蚀相关的体外镁腐蚀影响因素综述(英文)显示文摘本文通过综述相关文献,系统地评价了影响体外镁(Mg)腐蚀的因素.分析了以下因素对镁体外生物腐蚀的影响:(i)无机离子,包括阴离子和阳离子,(ii)有机成分,如蛋白质、氨基酸和维生素,(iii)实验参数,如温度、p H值、缓冲体系和流速.通过这些归纳分析,为建立一个体外生物腐蚀测试的标准化方法提供了思考和建议,并推荐了几种有潜力的模拟体液.实施实验参数的标准化方法具有显著减少体外生物腐蚀试验差异的潜能,并有助于建立准确一致模拟体内腐蚀的方法.然而,在如何更好地表征体内环境和腐蚀机理上尚存在着知识上的空白.本文审查了血浆是进行体外腐蚀测试的合适体液这一假设,并提出在今后研究中需进一步考虑影响体内腐蚀机理的因素,如样品封埋等. | Sean Johnston Matthew Dargusch Andrej Atrens | 2018 | Science China Materials2018，61，4： | 3 |

| 9 | The influence of Ca and Cu additions on the microstructure,mechanical and degradation properties of Zn-Ca-Cu alloys for absorbable wound closure device applications显示文摘Novel ternary Zn-Ca-Cu alloys were studied for the development of absorbable wound closure device material due to Ca and Cu’s therapeutic values to wound healing.The influence of Ca and Cu on the microstructure,mechanical and degradation properties of Zn were investigated in the as-cast state to establish the fundamental understanding on the Zn-Ca-Cu alloy system.The microstructure of Zn-0.5Ca-0.5Cu,Zn-1.0Ca-0.5Cu,and Zn0.5Ca-1.0Cu is composed of intermetallic phase CaZn13 distributed within the Zn-Cu solid solution.The presence of CaZn13 phase and Cu as solute within the Zn matrix,on the one hand,exhibited a synergistic effect on the grain refinement of Zn,reducing the grain size of pure Zn by 96%;on the other hand,improved the mechanical properties of the ternary alloys through solid solution strengthening,second phase strengthening,and grain refinement.The degradation properties of Zn-Ca-Cu alloys are primarily influenced by the micro-galvanic corrosion between Zn-Cu matrix and CaZn13 phase,where the 0.5%and 1.0%Ca addition increased the corrosion rate of Zn from 11.5μm/y to 19.8μm/y and 29.6μm/y during 4 weeks immersion test. | Nan Yang Nagasivamuni Balasubramani Jeffrey Venezuela Sharifah Almathami Cuie Wen Matthew Dargusch | 2021 | Bioactive Materials2021，6，5： | 2 |

| 11 | Manufacturing of graded titanium scaffolds using a novel space holder technique显示文摘To optimize both the mechanical and biological properties of titanium for biomedical implants,a highly flexible powder metallurgy approach is proposed to generate porous scaffolds with graded porosities and pore sizes.Sugar pellets acting as space holders were compacted with titanium powder and then removed by dissolution in water before sintering.The morphology,pore structure,porosity and pore interconnectivity were observed by optical microscopy and SEM.The results show that the porous titanium has porosity levels and pore size gradients consistent with their design with gradual and smooth transitions at the interfaces between regions of differing porosities and/or pore sizes.Meanwhile,the porous titanium has high interconnectivity between pores and highly spherical pore shapes.In this article we show that this powder metallurgy processing technique,employing the novel sugar pellets as space-holders,can generate porous titanium foams with well-controlled graded porosities and pore sizes.This method has excellent potential for producing porous titanium structures for hard tissue engineering applications. | Yunhui Chen Damon Kent Michael Bermingham Ali Dehghan-Manshadi Gui Wang Cuie Wen Matthew Dargusch | 2017 | Bioactive Materials2017，2，4： | 2 |
