摘要

加入0.3%～0.6%的混合稀土能使AZ31镁合金铸态组织得到细化

经热挤压后其力学性能更有所提高。挤压态在25℃时

抗拉强度为285～300MPa

伸长率为16%～21%。但稀土加入量>0.6%

其抗拉强度、伸长率有所下降。

Abstract

The as-cast microstructure of AZ31 magnesium alloy can be refined with 0.3%～0.6% MM（mistchmetal）

and mechanical properties of the alloy prepared are improved after hot extruding process.Tensile strength

elongation of the extruded alloy at room temperature reach 285～300 MPa and 16%～21%

respectively.However

with MM addition more than 0.6%

the tensile strength and elongation of the extruded alloy are decreased slightly.
