摘要
研究轧制方式对AZ31镁合金薄板组织和性能的影响。交叉轧制可使材料的延伸率显著提高,σ0.2和σb明显下降,加强了组织的均匀性和等轴性。交叉轧制的AZ31镁合金薄板具有良好的深冲性能。
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.
