研究不同轧制变形量对Mg-12Li-3AlSi合金板材组织和性能的影响规律。结果表明,随着轧制变形量的增加,合金的抗拉强度明显增加,伸长率先增后减,总轧制变形量控制在85%~90%之间可获得综合力学性能优良的合金。
Effect laws of different rolling deformation on the microstructure and mechanical properties of alloy plate Mg-12Li-3AlSi alloy were researched. The results show that with the increase of rolling deformation,tensile strength of the alloy increases significantly,and elongation increases first then decreases. The total rolling deformation is controlled between 85% and 90%,then Mg-12Li-3AlSi has excellent comprehensive mechanical properties.
