Indentation Size Effect of Co Based Alloys During the Microhardness Test
采用Hanemann法和PMT-3硬度计探讨了不同热处理的钴基合金维氏显微硬度荷载的依赖性,利用Meyer定律、Hays-Kendall模型和Bull的弹塑性变形模型对试验数据进行了分析.结果表明,对于同一试样,在外加荷载下,利用Hanemann法测得的显微硬度有所下降,而PMT-3硬度测试表现出相反的现象.Meyer硬度指数n随所谓标准硬度常量A线性减小;在试验误差允许范围内,利用其它模型测得的与荷载无关的显微硬度是恒定的;引起硬度荷载依赖性的…查看全部>>
The dependence of the microhardness load of cobalt base alloy with different heat treatment was discussed with Hanemann method and PMT-3 hardness meter,the experimental data were analyzed using Meyer's law,Hays-Kendall model and Bull's elastic-plastic deformation model.The results show that for the same sample,the microhardness measured by Hanemann method is reduced under the applied load,and the PMT-3 hardness test show the opposite phenomenon.The Meyer har…查看全部>>
