摘要(Abstract)：

采用光学显微镜、X射线衍射仪、万能材料试验机及扫描电镜等研究了轧制方式对传统重力铸造方法制备的ATZS3311合金的微观结构及高温力学性能的影响。结果表明,轧制方式对合金的微观结构及力学性能有显著影响。单向轧制的合金由于Mg_2Si相呈带状分布导致合金室温强度优于交叉轧制,但交叉轧制后Mg_2Si相分布更加均匀,其对合金高温强度的提升贡献显著。高温拉伸结果表明交叉轧制后的合金抗拉强度明显优于单向轧制的合金,经150℃和200℃拉伸后,其抗拉强度分别达到168 MPa和166 MPa,断裂伸长率可达28%和31%,以上结果表明交叉轧制可明显改善ATZS3311合金的高温力学性能。
