Compressive creep behavior of Mg-Sn binary alloy WEI Shang-hai(魏尚海), CHEN Yun-gui(陈云贵)?, TANG Yong-bai(唐永柏), LIU Ming(刘 明), XIAO Su-fen(肖素芬), ZHANG Xiao-ping(章晓萍), ZHAO Yuan-hua... at elevated temperature. The compressive creep behavior of ageing-treated Mg-xSn (x=3%, 5%) alloys was investigated at the temperatures of 423 and 473 K and the stresses from 25 MPa to 35 MPa. When......
-La and Mg2Sn compounds can improve the tensile properties and compressive creep resistance of the alloys. Key words: Mg-Sn-La alloy; microstructure; tensile properties; compressive creep behavior... in compressive creep resistance behavior. So the secondary creep rate decreases largely. At elevated temperature, the larger size of heat-resistant phase plays a more important role in compressive creep......
