Plastic deformation behavior of AZ80 magnesium alloy and isothermal extrusion process simulation

ionproduction Figure 14 for the exports of 200mm extruded product and simulated temperature at the measured temperature curve, we can see that the measured temperature lower than the simulation temperature, because the simulation system of environmental factors such as heat setting and a certain bias due to the actual situation. But overall,[link widoczny dla zalogowanych], the simulation results coincide with the actual result. p Quebec presented in Figure 14 200mm extruded products export measured at the temperature and simulated temperature curves Fig. 14Experimenttemperatureandsimulationtemperatureunderexport200mmofextrusionproduct3 Conclusion In this paper, high-strength high temperature deformation of AZ80 alloy and plastic deformation behavior of tube extrusion by hot compression test, microstructure analysis and finite element simulation obtained: 1) AZ80 magnesium alloy in high temperature plastic deformation of grains size with increasing temperature and decreasing strain rate increases, the high temperature of recrystallization to continuous dynamic recrystallization. 2) by finite element simulation of magnesium alloy AZ80 to carefully quantify the process of isothermal extrusion process parameters of extrusion process for the TL A pair of steering development to provide 0864208642O8642086 ∞ ∞ ∞ ∞ ∞ 154 Mechanical Engineering Volume 16 guidance. By adjusting the extrusion speed 2rnm / s ~ lmm / s, so that the alloy extrusion exit temperature maintained at 400 ℃ ~ 43o ~ C smaller scale fluctuations, thus ensuring the products of the stress and strain rate distribution rules, stability, and ensure that products tissue before and after the performance and stability.
