Effects of temperature and strain rate on critical damage value of AZ80 magnesium alloy XIA Yu-feng(夏玉峰), QUAN Guo-zheng(权国政), ZHOU Jie(周 杰) School of Materials Science and Engineering... of strain rate at a certain temperature. While under a certain strain rate, the critical damage value has little change with the increase of temperature. Key words: AZ80 magnesium alloy; critical damage......
Plastic deformation mechanisms of AZ31 magnesium alloy under high strain rate compression YANG Yong-biao(杨勇彪)1, 2, WANG Fu-chi(王富耻)1, TAN Cheng-wen(谭成文)1, WU Yuan-yuan(吴园园)1, CAI Hong-nian(才鸿年)1...: The twinning and slip activities of AZ31 magnesium alloy sheet at a strain rate of 1 200 s-1 were investigated. Dynamically mechanical properties of various oriented samples were measured using......
; Abstract: Strain rate sensitivity and tension/compression asymmetry of AZ31 magnesium alloy at different temperatures and strain rates were investigated. Both of mechanical behaviors are temperature dependent. Strain rate sensitivity......

Coupled Influence of Temperature and Strain Rate on Tensile Deformation Characteristics of Hot-Extruded AZ31 Magnesium AlloyYing Yan1,Wan-Peng Deng1,Zhan-Feng Gao1,Jing Zhu1,2,Zhong-Jun Wang2,Xiao-Wu... of temperature T and strain ratee on the deformation features of AZ31 Mg alloy,mechanical behaviors and microstructural evolutions as well as surface deformation and damage features were systematically examined......
for doctors to collect patients’ health status. Among them, flexible strain sensor has been widely used for its ability to detect the joint movement, muscle movement, respiratory rate, pulse, blood pressure..., diverse material selection, strong mechanical and electrical controllability and low cost. In practical application, flexible strain sensors need to face complex loading conditions (e.g., strain rate......
