Effect of solution treatment on mechanical properties and microstructure of EV31A magnesium alloy
The experiment studied the effect of solution temperature and solution time on the mechanical properties,microstrusture and fracture morphology of the EV31A magnesium alloy.The results show that when solution temperature is 520 ℃,mechanical properties of EV31A magnesium alloy are the best.When solution time is longer than 6 h,it has little effect on tensile strength and elongation of EV31 A magnesium alloy.The appropriate solution time should be 6-10 hours.
