摘要: The main research objective is to analyze the influence of deformation conditions on the critical damage factor of AZ80 magnesium alloy. A basic research approach that physical experiments and numerical simulation provide mutual support for the critical damage factor was established. As several series of billet samples had been compressed on heat physical simulation machine under different deformation temperatures and strain rates, the true stress-strain data collected resulted the performance of simulations. Simulation results show that the maximum damage value appears on the outer edge of upsetting drum, and damage softening behavior is more sensitive to strain rate. A concept of damage sensitive rate was brought forth and its values were computed. The intersection of line fitted and horizontal axis was obtained as the fracture step and its relative maximum damage value was as a critical damage factor. The critical damage value distribution computed shows that it is not a constant but a change with a range 0.0218-0.378, and it is more sensitive on strain rate than temperature.
