- Abstract
The hot compression deformation behavior of AE42 magnesium alloy was investigated at the temperature range from 250 to 450 , the strain rate range from 0.001 to10 s-1 and the maximum reduction of 60 %. The relationships between flow stresses, deformation temperatures and strain rates of AE42 magnesium alloy were analyzed. The constitutive equation at elevated temperature was given. The results show that the flow stress decreases with the increasing of deformation temperature and the decreasing of strain rate, which can be described by a constitutive equation in hyperbolic sine law as =A[sinh( )]nexp( Q/RT), and can also be described by Zener-Hollomon parameters, calculated A, , n and Q are 4.64×1012 s 1, 0.0151 MPa 1, 7.34 and 173.29 kJ/mol, respectively. The dominated soften mechanisms of the AE42 magnesium alloy transform from dynamic recovery to dynamic recrystallization with increasing of the temperature and decreasing of the strain rate.
