镁合金板材轧制工艺及组织性能分析

Research on Rolling Technology of Magnesium Alloy Sheets

在研究镁合金板材熔铸及加工工艺的基础上,以AZ31B镁合金为材料,以优化组织性能为目标,通过控制轧制温度、压下制度、控温轧制和退火制度,轧制出σb≥280MPa,σ0.2≥160MPa,δ≥16%的镁合金板材,所轧制出的板材成功地得到实际应用,并对工艺制度的合理性从理论上进行了分析。

Using AZ31B Mg alloy as starting material, taking of optiminging microstructure and performances as purpose, casting and processing technologies of Mg alloy were investigated： Through temperature control rolling, corresponding thickness reductions control and paper annealing, AZ31B Mg alloy sheets with 660 mm -1100 mm （width）×0.18 mm -0.40 mm （thickness） were produced. Their σb≥ 280 MPa, σ0.2≥160 MPa,δ ≥ 16%, The sheets have found their actual applications.
