Abstract

In the present work, hot compression tests of AZ80+Ce alloy as-casted were carried out on a Gleeble-3500 thermo-mechanical simulator in temperatures range of 325 – 400 at intervals 25 , at strain rates of 0.01, 0.1, 1 and 10 s-1, respectively. The tests data at true strains of 0.1, 0.2, 0.3 and 0.4 were employed for consti-tutive analysis following the Arrhenius equation. The material constants including n, , , and Q have been de-termined considering the strain compensation using the cubic polynomial fitting method. And then, incorpo-rating the strain compensation on the constitutive equations for experimental alloy is established.
