Damage Evolution Equation of AZ31B Magnesium Alloy during Superplastic Deformation

Abstract:

After superplastic tensile tests and quantitative analysis of cavity volume fraction, the damage evolution equation based on the law of the micro-damage evolution and statistical mechanics was derived out. The characteristic parameters of damage evolvement and critical value of damage variables are achieved from the experiments.
