变形态AZ80镁合金冲击性能研究

Study on Impact Property of Deformed AZ80 Magnesium Alloy

笔者对AZ80镁合金试样分别在0.001S^(-1)、0.1S^(-1)、10S^(-1)、1320S^(-1)、2020S^(-1)、3100S^(-1)六个应变率下进行冲击试验,金相显微镜对其进行金相组织观察,主要观察不同加载条件下AZ80镁合金的晶粒形貌,包括晶粒变形、尺寸及剪切带等。采用origin软件对试验数据进行处理,作出相应的曲线,研究其变化规律,分析应变速率、应力、应变等条件对AZ80镁合金组织与性能的影响,分析塑性变形过程中组织演变的规律和力学性能之间的关系。

This article on the AZ80 magnesium alloy samples respectively in 0.001S-1, 0.1S-1 , 10S-1, 1320S-1, 2020S-1, 3100S-1 six strain rate impact test, metallographic observation of metallographic microscope, to observe the morphology of AZ80 magnesium alloy under different loading conditions, including grain size and deformation, shear zone. The experimental data were processed by Origin software, make the corresponding curve study on the change rule, analysis, strain rate, stress, strain and other conditions on the microstructure and properties of 5Z80 magnesium alloy, plastic analysis The relationship between the law of microstructure evolution and mechanical properties during deformation.
