Abstract

Compression tests of Mg-4Al-3Ca1.5Zn-1Nd-0.2Mn Magnesium alloy as-extruded were carried out on the Gleeble-3500 thermo-mechanical simulator. The compression testing temperatures were in the range of 200–350 at intervals 50 , while the imposed constant true strain rates were 0.001, 0.01, 0.1, 1 and 10S-1.True stress–strain data were employed for constitutive analysis following the sine-hyperbolic Arrhenius equation. The related material constants n, and , as well as the activation energy Q for each temperature regime have been determined considering the strain compensation using the cubic polynomial fitting method. And then, incorporating the strain compensation on the constitutive equations for experimental alloy is established.
