采用拉伸试验方法研究了超晶和粗晶AZ31镁合金的显微组织和力学性能。结果表明,超晶粒(200 nm)AZ31镁合金具有较好的力学性能,拉伸强度达到315 MPa,断口具有典型的韧性和较深的韧窝,这与AZ31镁合金的晶粒细化有关。
In this paper, microstructure and mechanical properties of ultra-grain size and coarse-grain size bulk AZ31 magnesium alloy were evaluated using tensile testing. The ultra-grain size (200nm) bulk AZ31 magnesium alloy showed well mechanical properties with stronger tensile strength (315MPa), typical ductile fracture surface and deep dimples, which can be attributed to grain size refinement of bulk AZ31 magnesium alloy.
