Numerical Analysis on Flow Stress of AZ61B Magnesium Alloy during Hot Compression Simulation Testing
The flow stress-strain curves and other information during hot compression testing of AZ61B magnesium alloy was investigated by simulated test on Gleeble-1500D thermal-mechanical simulator. The relations between Z and other characteristic value, including peak stress, peak strain and grain size, was calculated by regression analysis. The mathematical model of flow stress was introduced to predict the flow stress. The predicting values is close to the experimental values with not more than 10% error.
