Microstructure Development of Twin Roll Cast AZ31 Sheet in the Pre-Deformation Deep Drawing Process
Warm deep drawing processing was used to improve the deep drawability of Twin Roll Cast AZ31B magnesium sheet. Conspicuous effects were obtained and the Limited Drawing Ratio value of the sheet was improved by about 50% after the pre-deformation. Influence factor on the drawability of Twin Roll Cast magnesium alloy sheet was also analyzed. Numerical simulation method and microstructure analysis method were used to discuss the mechanisms of formation and develop of Twin Roll Cast microstructure in the twin roll cast process and the pre-deformation process.
