Non-Isothermal Simulation of Warm Circular Cup Deep Drawing Processing of an AZ31 Magnesium Alloy Sheet

摘要

Due to their low density, high specific strength, and electromagnetic interference shielding, magnesium alloy sheets are increasingly used in automotive and electronics industries. However, magnesium alloy sheets are usually formed at an elevated temperature due to poor formability at room temperature. For the industrial use of magnesium alloy sheets, the mechanical properties at elevated temperatures and appropriate forming process conditions need to be developed. In this study, the warm deep drawing process of AZ31 sheets is numerically studied by non-isothermal simulation. The difference between the isothermal and non-isothermal simulation results and the progress of warm forming is also discussed. The drawn depth and thickness distribution obtained from non-isothermal simulation agreed well with experimental results.
