Abstract: The hot deformation behaviors of AZ80 magnesium alloys at different states (as-cast, (410 , 4 h) (410 , 16
−1 were investigated by hot compression test
h)) in the temperature range of 250−400 and strain rate range of 0.002−1 s
on a Gleeble−1500D simulator. Based on these data, three processing maps were developed to assist in the analysis of the
influence of homog
