Sažetak

The hot deformation characteristics of deformed AZ81 magnesium alloy were studied by hot compression deformation on Gleeble-3800 thermal simulation test machine. The deformation temperatures were set at 300, 350, 400 and 450 °C, and the deformation rates were 0,01, 0,1 and 1s-1, respectively. Using the experimental data, the constitutive equation is obtained by friction correction and a series of formulas, and the constitutive equation is compared with the experimental data to verify its accuracy.
