The purpose of this research work was to develop a novel heat treatable wrought magnesium based alloy, which exhibits excellent strength and room temperature formability. As a result of alloy search using cast alloys, a Mg-Sn-Zn-Al alloy was found to exhibit substantial precipitation hardening. The extrusion condition and heat treatment schedule (e.g., solution treatment and aging treatment) were optimized based on the detailed nano-/micro-structure characterization by SEM, TEM and 3D atom probe. The newly developed Mg-Sn-Zn-Al extruded alloy exhibited high yield strength of over 350 MPa along with the large elongation to failure up to 15 % after aging treatment.

本研究的目的是开发一种新型的可热处理变形镁基合金，它具有优异的强度和室温成形性。作为使用铸造合金的合金研究的结果，发现Mg-Sn-Zn-Al合金表现出显著的沉淀硬化。挤出条件和热处理方案（例如，通过SEM、TEM和3D原子探针对合金的纳米/微米结构进行表征，优化了合金的固溶处理和时效处理工艺。新开发的Mg-Sn-Zn-Al挤压合金具有超过350 MPa的高屈服强度沿着在时效处理后具有高达15%的大的断裂伸长率。
