| 2 | Recent advances in biodegradation controls over Mg alloys for bone fracture management: A review显示文摘Magnesium(Mg) alloys possess comparable physical and mechanical properties to bone, making them an outstanding candidate of implant materials for bone fracture treatment. In addition to the excellent biocompatibility, and bioactivity, the engagement of Mg alloys is key for a number of biological functionalities in the human body. The unique biodegradation nature of Mg alloy implants implies that it may not require a secondary removal procedure when the expected supporting tasks accomplish, as they may simply and safely 'disappear' over time. Nonetheless, the demonstrated drawback of potentially rapid degradation, is an issue that must be addressed appropriately for Mg implants and is consequently given unique attention in this review article. Herein, the critical criteria and the state-of-the-art strategies for controlling the degradation process of Mg alloys are reported. Furthermore, future developments of biodegradable Mg and its alloys systems with satisfactory specifications for clinical trials and deployment,are discussed. This review aims to provide information to materials scientists and clinical practitioners in the context of developing practical biodegradable Mg alloys. | Ming-Shi Song Rong-Chang Zeng Yun-Fei Ding Rachel W.Li Mark Easton Ivan Cole Nick Birbilis Xiao-Bo Chen | 2019 | Journal of Materials Science & Technology2019，35，4： | 26 |
| 3 | Application of Lanthanum in High Strength and High Conductivity Copper Alloys显示文摘China is quite poor in argent resource. Roughly 80% of this industrial argent is imported every year. In order to improve the situation, we took advantage of rare earth (RE) mineral resource and successfully developed the non-argent Lanthanum-tellurium-copper alloy as a substitute for industry argent-copper. In our research, we were able to successfully apply rare earth lanthanum to copper alloy. The defects as porosity, inclusion, etc. originating from nonvacuum melting processing were controlled. Fine grain was obtained. Meanwhile, the comprehensive properties of the copper alloy, such as strength, conductivity and thermal conductivity were improved. The research results in increasing conductivity and thermal conductivity by 5% and 15%, respectively, while the tensile strength is increased by 6% higher than Ag-Cu alloy. The anti-electric corrosion property is good, and there is no argent-cadmium steam population originating from the electric arc effect. The addition of lanthanum further reduces the content of oxygen and hydrogen.The optimum quantity of the addition of RE lanthanum in the copper alloy is 0.010%~0.020%. | 周世杰 赵秉钧 赵桢 金鑫 | 2006 | Journal of Rare Earths2006，24，z2： | 22 |

| 5 | Mn含量对Mg-Zn-Mn变形镁合金显微组织和力学性能的影响显示文摘通过对3种不同Mn含量的Mg-6Zn-XMn变形镁合金的微观组织的观察及力学性能的测定,研究了Mn含量对Mg-Zn-Mn镁合金显微组织和力学性能的影响。结果表明:Mn元素以单质形式弥散地分布于Mg-Zn-Mn合金中,起到阻碍晶粒长大的作用,即随着Mn含量的增加,晶粒尺寸减小;Mn含量的变化对合金的屈服强度有一定的影响,即随着Mn含量的增加,屈服强度增加,其中挤压态增幅最大,双级时效次之,增幅分别是14%和5%;而Mn含量的变化对T6、T4+双级时效后合金的抗拉强度和延伸率的影响规律不明显,其中含0.68%Mn(质量分数,下同)的合金整体性能较优,经双级时效后具有最高抗拉强度,达到360MPa,伸长率为5.2%。 | 张丁非 齐福刚 石国梁 戴庆伟 | 2010 | 稀有金属材料与工程2010，39，12： | 16 |
| 6 | Corrosion resistance of in-situ growth of nano-sized Mg(OH)2 on micro-arc oxidized magnesium alloy AZ31—Influence of EDTA显示文摘One of the major obstacles for the clinical use of biodegradable magnesium(Mg)-based materials is their high corrosion rate. Micro-arc oxidation(MAO) coatings on Mg alloys provide mild corrosion protection owing to their porous structure. Hence, in this study a dense Mg(OH)2 film was fabricated on MAO-coated Mg alloy AZ31 in an alkaline electrolyte containing ethylenediamine tetraacetic acid disodium(EDTA-2 Na) to reinforce the protection. Surface morphology, chemical composition and growth process of the MAO/Mg(OH)2 hybrid coating were examined using field-emission scanning electron microscopy, energy dispersive X-ray spectrometer, X-ray diffraction, X-ray photoelectron spectroscopy and Fourier transform infrared spectrophotometer. Corrosion resistance of the coatings was evaluated via potentiodynamic polarization curves and hydrogen evolution tests. Results manifested that the Mg(OH)2 coating possesses a porous nano-sized structure and completely seals the micro-pores and micro-cracks of the MAO coating.The intermetallic compound of AlMn phase in the substrate plays a key role in the growth of Mg(OH)2 film. The current density of Mg(OH)2-MAO composite coating decreases three orders of magnitude in comparison with that of bare substrate, indicating excellent corrosion resistance. The Mg(OH)2-MAO composite coating is beneficial to the formation of calcium phosphate corrosion products on the surface of Mg alloy AZ31, demonstrating a great promise for orthopaedic applications. | Chang-Yang Li Xiao-Li Fan Rong-Chang Zeng Lan-Yue Cui Shuo-Qi Li Fen Zhang Qing-Kun He M.

| 7 | DISLOCATION DISSOCIATIONS AND FAULTENERGIES IN Ni_3Al ALLOYS DOPED WITH PALLADIUM显示文摘Dislocation structures in polycrystalline Ni 3Al alloy doped with palladium deformed at room temperature have been investigated by transmission electron microscopy. The structure consists mainly of dislocations dissociated into a /2〈011〉 super partials bounding an anti phase boundary (APB). Dislocations dissociated into a /3〈112〉 super Shockley partials bounding a superlattice intrinsic stacking fault (SISF) are also common debris. The majority of the SISFs are truncated loops, i.e. the partials bounding the SISF are of similar Burgers vector. These faulted loops are generated from APB coupled dislocations, according to a mechanism for formation of SISFs proposed by Suzuki et al , and recently modified by Chiba et al . The APB energies for {111} and {010} slip planes are measured to be 144±20 mJ/m 2 and 102±11 mJ/m 2 respectively, and the SISF energy has been estimated to be 12 mJ/m 2 in this alloy. It is concluded that the dislocation structure in Ni 74.5 Pd 2Al 23.5 alloy deformed at room temperature is similar to that in binary Ni 3Al, and the difference in fault energies between these two alloys is small. Thus, it seems unlikely that the enhancement of ductility of Ni 74.5 Pd 2Al 23.5 results from only such a small decrease of the ordering energy of the alloy. SISF bounding dislocations also have no apparent influence on the ductilization of Ni 74.5 Pd 2Al 23.5 alloy. | J. Sun *# , C. S. Lee # and J. K. L.

| 8 | Machine learning guided appraisal and exploration of phase design for high entropy alloys显示文摘High entropy alloys(HEAs)and compositionally complex alloys(CCAs)have recently attracted great research interest because of their remarkable mechanical and physical properties.Although many useful HEAs or CCAs were reported,the rules of phase design,if there are any,which could guide alloy screening are still an open issue.In this work,we made a critical appraisal of the existing design rules commonly used by the academic community with different machine learning(ML)algorithms.Based on the artificial neural network algorithm,we were able to derive and extract a sensitivity matrix from the ML modeling,which enabled the quantitative assessment of how to tune a design parameter for the formation of a certain phase,such as solid solution,intermetallic,or amorphous phase.Furthermore,we explored the use of an extended set of new design parameters,which had not been considered before,for phase design in HEAs or CCAs with the ML modeling.To verify our ML-guided design rule,we performed various experiments and designed a series of alloys out of the Fe-Cr-Ni-Zr-Cu system.The outcomes of our experiments agree reasonably well with our predictions,which suggests that the ML-based techniques could be a useful tool in the future design of HEAs or CCAs. | Ziqing Zhou Yeju Zhou Quanfeng He Zhaoyi Ding Fucheng Li Yong Yang | 2019 | npj Computational Materials2019，，1： | 16 |

| 10 | Fatigue crack initiation of magnesium alloys under elastic stress amplitudes:A review显示文摘The most advantageous property of magnesium(Mg)alloys is their density,which is lower compared with traditional metallic materials.Mg alloys,considered the lightest metallic structural material among others,have great potential for applications as secondary load components in the transportation and aerospace industries.The fatigue evaluation of Mg alloys under elastic stress amplitudes is very important in ensuring their service safety and reliability.Given their hexagonal close packed structure,the fatigue crack initiation of Mg and its alloys is closely related to the deformation mechanisms of twiuning and basal slips.However,for Mg alloys with shrinkage porosities and inclusions,fatigue cracks will preferentially initiate at these defects,remarkably reducing the fatigue lifetime.In this paper,some fundamental aspects about the fatigue crack initiation mechanisms of Mg alloys are reviewed,in cluding the 3 followings:1)Fatigue crack initiation of as-cast Mg alloys,2)influence of microstructure on fatigue crack initiation of wrought Mg alloys,and 3)the effect of heat treatment on fatigue initiation mechanisms.Moreover,some unresolved issues and future target on the fatigue crack initiation mechanism of Mg alloys are also described. | B.J.WANG D.K.XU S.D.WANG E.H.HAN | 2019 | Frontiers of Mechanical Engineering2019，14，1： | 15 |
| 11 | Preparation of 2024/3003 gradient materials by semi-continuous casting using double-stream-pouring technique显示文摘The 2024/3003 aluminum gradient alloys are prepared by semi continuous casting. The influences of throttle bore diameter of embedded nozzle and temperature of internal melt on composition distribution, macrostructure, hardness are analyzed, and the stability of gradient distribution of composition, macrostructure and hardness along the axial direction of the ingot is also studied. The results show that diffe rent composition profiles can be achieved by adjusting the processing parameters; the volume fraction of inner alloy in the ingot can be increased by enlarging the throttle bore diameter and elevating the temperature of inner melt; quasi steady solidification can be realized within 20 s during cast processing, and consistent quality ingot is obtained by controlling the casting speed and liquid height of inner melt. | 李元元 费劲 陈维平 张卫文 邵明 | 2002 | Journal of Central South University of Technology2002，9，4： | 14 |

| 13 | In vitro corrosion resistance and antibacterial performance of noveltin dioxide-doped calcium phosphate coating on degradable Mg-1Li-1Ca alloy显示文摘A SnO_2-doped calcium phosphate(Ca-P-Sn) coating was constructed on Mg-1 Li-1 Ca alloy by a hydrothermal process. The fabricated functional coatings were investigated using scanning electron microscopy(SEM), X-ray diffraction(XRD) and Fourier transform infrared spectroscopy(FT-IR). A triple-layered structure, which is composed of Ca_3(PO_4)_2,(Ca, Mg)_3(PO_4)_2, SnO_2, and MgHPO_4·3 H_2O, is evident and leads to the formation of Ca_(10)(PO_4)_6(OH)_2 in Hank's solution. Electrochemical measurements, hydrogen evolution tests and plating counts reveal that the corrosion resistance and antibacterial activity were improved through the coating treatment. The embedded SnO_2 nanoparticles enhanced crystallisation of the coating.The formation and degradation mechanisms of the coating were discussed. | Lan-Yue Cui Guang-Bin Wei Zhuang-Zhuang Han Rong-Chang Zeng Lei Wang Yu-Hong Zou Shuo-Qi Li Dao-Kui Xu Shao-Kang Guan | 2019 | Journal of Materials Science & Technology2019，35，3： | 14 |

| 15 | Deposition of FeCoNiCrMn high entropy alloy(HEA) coating via cold spraying显示文摘High entropy alloys(HEAs) are of great interest in the community of materials science and engineering due to their unique phase structure. They are constructed with five or more principal alloying elements in equimolar or near-equimolar ratio. Therefore, HEAs can derive their performance from multiple principal elements rather than a single element. In this work, solid-state cold spraying(CS) was applied for the first time to produce FeCoNiCrMn HEA coating. The experimental results confirm that CS can be used to produce a thick HEA coating with low porosity. As a low-temperature deposition process, CS completely retained the HEA phase structure in the coating without any phase transformation. The characterization also reveals that the grains in the CSed HEA coating had experienced significant refinement as compared to those in the as-received HEA powder due the occurrence of dynamic recrystallization at the highly deformed interparticle region. Due to the increased dislocation density and grain boundaries,CSed HEA coating was much harder than the as-received powder. The tribological study shows that the CSed FeCoNiCrMn HEA coating resulted in lower wear rate than laser cladded HEA coatings. | Shuo Yin Wenya Li Bo Song Xingchen Yan Min Kuang Yaxin Xu Kui Wen Rocco Lupoi | 2019 | Journal of Materials Science & Technology2019，35，6： | 13 |
| 16 | A property-oriented design strategy for high performance copper alloys via machine learning显示文摘Traditional strategies for designing new materials with targeted property including methods such as trial and error,and experiences of domain experts,are time and cost consuming.In the present study,we propose a machine learning design system involving three features of machine learning modeling,compositional design and property prediction,which can accelerate the discovery of new materials.We demonstrate better efficiency of on a rapid compositional design of high-performance copper alloys with a targeted ultimate tensile strength of 600–950 MPa and an electrical conductivity of 50.0%international annealed copper standard.There exists a good consistency between the predicted and measured values for three alloys from literatures and two newly made alloys with designed compositions.Our results provide a new recipe to realize the property-oriented compositional design for highperformance complex alloys via machine learning. | Changsheng Wang Huadong Fu Lei Jiang Dezhen Xue Jianxin Xie | 2019 | npj Computational Materials2019，，1： | 12 |
| 17 | Progress in preparation of rare earth metals and alloys by electrodeposition in molten salts显示文摘Rare earth(RE) metals and their alloys have attracted considerable practical interests due to their functional properties. Because of their negative deposition potentials, RE metals cannot be electrochemically deposited from aqueous media. Using molten salt as medium provides a unique opportunity for the electrowinning and electrore?ning of high-purity RE metals, as well as for the electrochemical formation of their alloys and intermetallic compounds. Certainly, the electrochemical behaviors of RE metals and their alloys have been investigated in a number of different molten salts comprising all-?uorides,all-chlorides and mixed chloride-?uoride media. Based on the results, RE and their alloys were produced by molten salt electrolysis. In this paper, the developments of preparation of RE metals and their alloys by electrolysis in molten salts in recent years were systematically summarized on both the local and international levels. Attention was paid mainly to the electrodeposition of RE metals and their alloys, including RE–Mg, RE–Al, RE–Ni, RE–Co,RE–Cu, RE–Fe and RE–Zn alloys. | Wei Han Mei Li Mi-Lin Zhang Yong-De Yan | 2016 | Rare Metals2016，35，11： | 11 |
| 18 | Strengthening FCC-CoCrFeMnNi high entropy alloys by Mo addition显示文摘In order to strengthen the face-centered-cubic(FCC) type CoCrFeMnNi high entropy alloys(HEAs), different contents of Mo(0–16 at.%, similarly hereinafter) were alloyed. Phase evolution, microstructure,mechanical properties and related mechanism of these HEAs were systematically studied. The results show that sigma phase is appeared with addition of Mo, and the volume fraction of it increases gradually from 0 to 66% with increasing Mo content. It is found that Mo is enriched in sigma phase, which indicates that Mo element is beneficial to form sigma phase. Compressive testing shows that the yield strength of the alloys increases gradually from 216 to 765 MPa, while the fracture strain decreases from 50%(no fracture) to 19% with increasing of Mo. The alloy exhibits the best compressive performance when Mo content reaches 11%, the yield strength, fracture strength and fracture strain are 547 MPa, 2672 MPa and44% respectively. The increased volume fraction of sigma phase plays an important role in improving the compressive strength of(CoCrFeMnNi)_(100-x)Mo_xHEAs. | Gang Qin Ruirun Chen Huiting Zheng Hongze Fang Liang Wang Yanqing Su Jingjie Guo Hengzhi Fu | 2019 | Journal of Materials Science & Technology2019，35，4： | 11 |
| 19 | Effect of long-period stacking ordered phase on microstructure,mechanical property and corrosion resistance of Mg alloys: A review显示文摘Magnesium alloys containing long period stacking ordered(LPSO) phase have been received a great deal of attention in the last decade owing to their excellent comprehensive properties of mechanical strength and corrosion resistance. In this paper, some fundamental aspects of LPSO containing Mg alloys have been reviewed, including:(1) microstructural characterization, formation conditions and the associated phase transformation of LPSO phases in Mg alloys;(2) deformation mechanism of LPSO phases and their in fl uence on the deformation mechanism of the Mg matrix;(3) effect of LPSO structure on the mechanical performance such as tensile strength, creep resistance, fracture toughness and fatigue strength;(4) corrosion behavior of LPSO containing Mg alloys and their possible applications as the biomaterials.Moreover, some remaining unsolved issues of the LPSO containing Mg alloys and the future target about how to further improve their service properties have been also described. | Daokui Xu En-hou Han Yongbo Xu | 2016 | Progress in Natural Science:Materials International2016，26，2： | 11 |
| 20 | Structural evolution of non dendritic AlSi7Mg alloy during reheating显示文摘The structural evolution of non dendritic AlSi7Mg alloy during reheating in resistance furnace was studied. The alloy ingots were produced by electromagnetic stirring during solidification. It was found that, the Si phase in eutectic dissolves in a way of diffusion toward α phase, its appearance changes from flake to dot like, and tends to be fine and spheroidal with increasing reheating temperature. The thinner the flake, the lower the temperature for the occurrence of this process, and the higher the transforming speed. The eutectic melts partially when Si phase dissolves to some extent, and the morphology and size of primary α phase begin to change. The dendrite and rosette α phases tends to sphericize. The size of the former becomes larger, while the size of the latter reduces to be 1/2~1/4 of the original size. The spheroidal primary α phase has a tendency of grain growth. | Zhang Kui(张奎) Zhang Yongzhong(张永忠) Liu Guojun(刘国均) Xu Jun(徐骏) Zhang Jingxin(张景新) Fan Jianzhong(樊建中) Shi Likai(石力开) | 1999 | 中国有色金属学会会刊:英文版1999，9，3： | 10 |
