A constitutive relation of AZ80 magnesium alloy during hot deformation based on Arrhenius and Johnson–Cook model
In order to understand the constitutive behavior of as-cast AZ80 with large grain size, the uniaxial hot compression tests were carried out over a series of isothermal upsetting experiments. The maximum deformation degree was 65%. The experimental temperatures were 523 K, 573 K, 623 K and 673 K and...
