The Formability and Hot Stamping of Magnesium Alloy Sheets

Abstract:

Mg alloy is a potential material to be used in automobile, especially in the stamping products. Through texture weakening, temperature increasing, strain rate decreasing, blank holder force controlling, lubrication choosing and so on, the formability of AZ31 magnesium alloy is improved so that the cold stamping on some simple products can be conducted. However, on the complicated products, hot stamping should be considered. Temperature has an important effect on the formability of Mg alloy sheet. As the temperature increasing, the strength of Mg alloys sheet decreases while the formability increases. Hot stamping process is an effective way to broaden the using of Mg alloys.
