摘要
采用不同的挤压温度对汽车零件用Mg-8Al-3Sn-0.5V镁合金试样进行了挤压试验,并进行了力学性能和显微组织的测试与分析。结果表明:随挤压温度的升高,试样的抗拉强度、屈服强度先增大后减小,断后伸长率先减小后增大。在340℃挤压后,试样的抗拉强度、屈服强度最大,断后伸长率最小。汽车零件用Mg-8Al-3Sn-0.5V镁合金试样的挤压温度优选340℃。
Extrusion tests of Mg-8 Al-3 Sn-0.5 V magnesium alloy samples for automobile parts were carried out at different extrusion temperatures. The mechanical properties and microstructure were tested and analyzed. The results show that with the increase of extrusion temperature, the tensile strength and yield strength first increase and then decrease, and the elongation after fracture first decreases and then increases. After extrusion at 340 ℃, the tensile strength and yield strength of the sample are the highest, and the elongation after break is the smallest. The extrusion temperature of Mg-8 Al-3 Sn-0.5 V magnesium alloy specimens for automotive parts is preferably 340℃.
