Hot-compression constitutive relation of as-cast AZ31 magnesium alloy

摘要：

In hot-compression process,the various factors have obvious effects on the deformation behavior of AZ31 magnesium alloy deformation behavior.To understand the hot-compression constitutive relation thoroughly,the stress-strain behavior of AZ31 magnesium alloy at various strain rates and different deformation temperatures were investigated under maximum strain of 60％.The microstructure of the experimental alloy was studied in the hot-compression procedure.The experimental results show that the relation of peak flow stress,strain rate and temperature can be described by Z parameter which contains Arrheniues item.The strain rate and the deformation temperature are the key parameters affecting deformation activation energy.
