ABSTRACT In this study, pre-deformation followed by heat treatment for enhancing the formability of AZ31-0.5Ca magnesium alloy was investigated. For this purpose, alloy samples were subjected to tensile deformation at various amounts of strains (5%, 10%, and 15%) followed by heat treatment at 260°C for 30 min. The results showed that the 5%-deformed sample exhibited a coarser-grained structure as compared to 10%- and 15%-deformed samples and weaker basal texture as compared to that of the non-deformed sample. The evolution of such structure resulted in improved stretch formability of this alloy sample.

提高镁合金室温拉伸成形性的结构优化

摘要 在这项研究中，研究了预变形和热处理以提高 AZ31-0.5Ca 镁合金的可成形性。为此，合金样品在不同的应变量（5%、10% 和 15%）下进行拉伸变形，然后在 260°C 下热处理 30 分钟。结果表明，与10%和15%变形的样品相比，5%变形的样品表现出更粗的晶粒结构，并且与未变形的样品相比，基底质地更弱。这种结构的演变导致该合金样品的拉伸成形性得到改善。
