摘要:为了改善AZ80镁合金的凝固组织,提高其力学性能,采用光学显微镜、维氏硬度、极限拉伸强度和压缩屈服强度等试验手段,评价不同冷却速度对AZ80镁合金表面微观形貌和力学性能的影响。结果显示,合金的冷却速度能够显著影响AZ80镁合金凝固组织和力学性能。随着冷却速度的增加,AZ80镁合金的硬度、极限拉伸强度和压缩屈服强度等力学性能随之增加。为了提高AZ80镁合金的力学性能,应该提高AZ80镁合金溶体的冷却速度。
To improve the surface mierostructure and the mechanical properties of AZ80 magnesium alloy, the effect of cooling rates on the solidification microstructure and the mechanical properties of AZ80 magnesium alloy was investigated by optical microscope and testing method of Vickers hardness, ultimate tensile strength and yield strength. The results show that the cooling rates has a significantly effect on solidification microstructure and mechanical properties of AZ80 alloy. With the increase of cooling rate, Vickers hardness, ultimate tensile strength and yield strength of AZ80 magnesium alloy improve obviously. In order to improve the mechanical properties of AZ80 magnesium alloy, the higher cooling rate is necessary.
