Study on critical damage factor and the constitutive model including dynamic recrystallization softening of AZ80 magnesium alloy

Quantities AZ80 magnesium alloy billets were compressed with 60 % height reduction on hot process simulator at 473, 523, 573, 623, 673, 723 K under strain rates of 0.001, 0.01, 0.1, 1 and 10 s-1. In order to predict the occurrence of surface fracture, the critical damage factor based on the Cock...
