摘要 研究了Mg-2Zn-Mn-0.5Nd镁合金不同挤压温度对其制品组织和性能的影响及作用机理。结果显示:挤压温度从340℃提高到420℃时,合金的室温伸长率可从14%左右提高到26%以上,伴随强度明显下降。挤压温度从340℃降低到260℃时,合金的伸长率也提升到19%,而强度减弱不明显。分析表明:合金的晶粒尺寸和织构强弱等因素,共同决定该合金挤压制品的室温力学性能。

Abstract:The effects and the action mechanism of extruded temperature on microstructure and mechanical properties of as-extruded Mg-2Zn-Mn-0.5Nd alloy were investigated. The result shows that when the extruded temperature changes from 340℃ to 420℃, the room temperature elongation raises from 14% to 26%, meanwhile the strength obviously decreases; When the extruded temperature changes from 340℃ to 260℃, the room temperature elongation can also be increased from 14% to 19%, but ultimate tension strength (UTS) and yield strength (YS) have no obvious decrease. The analysis shows that the grain size and the texture intensity of the alloy are the joint factors to decide the mechanical properties of the as-extruded Mg-2Zn-Mn-0.5Nd alloy.
Key wordsMg-2Zn-Mn-0.5Nd alloy    extruded temperature    microstructure    mechanical property    texture
