Effect of Deformation Condition on the Mechanical Behavior of AZ80 Magnesium Alloy

Abstract:

Article Preview

With the deformation temperature between 250°C and 450°C as well as the strain rate between 0.01s-1 and 5s-1, the hot compression tests of AZ80 magnesium alloy were performed on Gleeble-3800 thermal simulation testing machine, so as to seek out the responses of mechanical behavior of AZ80 magnesium alloy under different deformation conditions. The results indicated that AZ80 magnesium alloy shows dynamical recrystallization when hot compessed, the recrystallization is prone to happen and the stress peak decreases with the temperature increased, and the critical strain to produce the transformation of recrystallization augments with the strain rate increased.
