本研究的目的是开发一种具有优异强度和室温成形性的可热处理变形镁基合金。使用铸造合金进行合金搜索,发现Mg-Sn-Zn-Al合金表现出明显的沉淀硬化。通过扫描电镜、透射电镜和三维原子探针的详细表征,优化了挤压条件和热处理工艺(如固溶处理和时效处理)。新研制的Mg-Sn-Zn-Al挤压合金的屈服强度超过350 MPa,时效后的失效伸长率高达15%。
英文摘要
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.
