Abstract: The effect of rolling method on microstructure and properties of a AZ31 magnesium alloy thin sheet were investigated. The results show that the elongation can be increased apparently by cross rolling, while the ultimate tensile strength and the yield strength are decreased. The uniformity and the spheroidicity of the microstructure are improved. The heat stamping experiment proves the deep drawing property of AZ31 magnesium alloy thin sheet.
Key words: AZ31 magnesium alloy; cross rolling; microstructure and property; heat stamping
