主 题:AZ41 alloy flow stress deformation behavior dynamic model twin-roll casting hot compression
摘 要:A dynamic material model of Mg-4.51Al-1.19Zn-0.5Mn-0.5Ca(AZ41,mass fraction,%)magnesium alloy was put *** results show that the dynamic material model can characterize the deformation behavior and microstructure evolution and describe the relations among flow stress,strain,strain rates and deformation *** analysis shows the validity of the proposed *** model predicts that lower deformation temperature and higher strain rate cause the sharp strain hardening. Meanwhile,the flow stress curve turns into a steady state at high temperature and lower strain *** moderate temperature of 350 ℃and strain rate of 0.01 s-1 are appropriate to this alloy.
