Damage Evolution Equation of AZ31B Magnesium Alloy during Superplastic Deformation

摘要：

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.
