采用金相显微镜、扫描电镜及能谱分析等手段

研究了Mg-1Er-0.6Zr合金在铸态、挤压态和时效态的室温组织和力学性能。结果表明

在温度为300℃

挤压比为16:1时

合金的抗拉强度、屈服强度和伸长率分别为206.5MPa、78.5MPa和25%

比铸态时分别提高了28.4%、8.6%和150%。挤压后时效处理

强度稍有提高;但固溶后再时效其强度明显降低

塑性也有所降低。

Microstructure and mechanical properties of Mg-1Er-0.6Zr alloys in as-cast

extruded and aged state were investigated by means of optical microscope（OM）

scanning electron microscope（SEM）and energy spectrum analysis（EDS）.The results show that the tensile strength

yield strength and elongation of as-extrued Mg-1Er-0.6Zr alloy at 300 ℃ with extrusion ratio of 16 reach 206.5 MPa

78.5 MPa and 25%

respectively

improved by 28%

8% and 150%

comparing to those of the as-cast alloy.The strength of the extruded alloy after aging treatment is increased slightly

however

it is greatly decreased after solid solution with re-aging treatment

and elongation is decreased slightly also.
