description | The hot deformation characteristics of a AZ81E magnesium alloy are studied in the RANGE temperatures from 340 to 430 °C and strain rates ranging between 0.003 and 3.0 s−1 utilizing hot compression tests. Combining Arrhenius equation and Zener-Hollomon parameter, the high temperature flow stress model is proposed and the average activation energy is 166.15 kJ/mol. Processing maps for hot working are developed on the basis of the efficiency of power dissipation with changing temperatures and strain rates. The power dissipation map reveals that the optimum hot working domain is the temperature range of 390–400 °C and strain rate range of 0.03–0.3 s−1. |
