Thermal Deformation Property and Constitutive Model of AZ80 Magnesium Alloy

Abstract:

Thermal Deformation Property and Constitutive Model of AZ80 Magnesium Alloy had been studied with thermal simulation experiment. Dynamic recrystallization for AZ80 magnesium alloy had occurred under different strain rate at 583K(310°C). Dynamic recrystallization had occurred more completely and the grain size was reducing with increasing of strain rate. Dynamic recrystallization had occurred more completely and the grain size was reducing with increasing of strain rate. According the Arrhenius equation, a kind of constitutive equation of AZ80 Magnesium alloy which considered the strain had been put forward, and the relative errors between calculation results by the stress-strain model and experiment results are less than 10.5%.
