TENSILE STRENGTH AND CREEP RESISTANCE OF Mg-9Al-1ZnBASED ALLOYS WITH CALCIUM ADDITION Y.S.Sun1,W.M.Zhang1,X.G.Min1 (1.Department of Materials Science and Engineering, Southeast University, Nanjing... with the increase of Ca addition and maximum strength was obtained from the alloy containing 0.15% of Ca. The creep resistance at the temperatures between 150-200°C was also significantly increased......
Microstructure and tensile creep resistance ofMg-5.5%Zn-(0.7%, 1.5%, 3.5%, 7.5%)Y alloysCHEN Gang(陈刚), ZHANG Yan-bin(张艳斌), XIA Wei-jun(夏伟军), CHEN Ding(陈鼎)(College of Materials Science and Engineering, Hunan University, Changsha 410082, China)Abstract:Thetensile creep resistance of Mg-5.5%Zn-(0.7%,1.5%,3.5%,7.5%)Y(mass fraction, %) gravity-casting alloys was investigated systematically......
℃ for 100 h. Key words: Ti-600 alloy; high temperature titanium alloy; tensile property; creep resistance creep properties. As compressor disc and blade for high ratio aero-engines, higher creep resistance are required for high temperature Ti alloys used at 600......
matrix can be observed on the dislocation line. Dislocations are pinned by these precipitates which can effectively obstruct dislocation motion, thereby, improving the creep resistance of the alloy... Creep properties and controlled creep mechanism of as-cast Mg-5Zn-2.5Er alloy LI Han(李 晗), DU Wen-bo(杜文博), LI Jian-hui(李建辉), LI Shu-bo(李淑波), WANG Zhao-hui(王朝辉) School of Materials Science......
Microstructure, tensile properties and compressive creep resistance of Mg-(5-8.5)%Sn-2%La alloys ZHANG Xiao-ping(章晓萍), CHEN Yun-gui(陈云贵), XIAO Su-fen(肖素芬), TANG Yong-bai(唐永柏..., tensile properties and compressive creep resistance of permanent-mould cast Mg-(5-8.5)%Sn-2%La (mass fraction) alloys were investigated. The results show that Mg-(5-8.5)%Sn-2%La alloys are all composed......
the tin content varies, the ageing-treated Mg-xSn alloys show quite different creep resistance, which are mainly attributed to the size and distribution of Mg2Sn phases in the ageing-treated Mg-xSn alloys... at present. However, Mg-Al alloy system particularly with high Al content shows poor creep resistance at elevated temperatures, since β-Mg17Al12 phase in Mg-Al alloys is not a good strengthening phase......
creep resistance of Mg-Y-Nd alloys[10-12]. The steady state creep properties of squeeze-cast Mg-3Y- 2Nd-1Mn alloy modified by 1% (mass fraction) of Zn at 300 ℃ in the stress range between 30 and 80... (-Zn) casting [J]. Material Science Forum, 2003, 419/422: 276-281. [2] NIE J F, GAO X, Zhu S M. Enhanced age hardening response and creep resistance of Mg-Gd alloys containing Zn [J]. Scripta......
properties must be achieved by designing and constructing more suitable microstructure,such as hierarchical microstructure.In order to significantly enhance the creep resistance of titanium matrix... resistance could be attributed to the hierarchical microstructure.The micro-TiBw reinforcement in the first-scale network boundary contributed to creep resistance primarily by blocking grain boundary......
