【摘要】 通过与拉伸试验结果的对比,对弯曲法在金属微塑变测试中的可行性进行了进一步的分析与论证。在此基础上通过对LD2、1Cr18Ni9Ti及H62等材料的微塑变测试,讨论了弯曲法的尺寸效应、误差来源及其修正方法。更多还原

【Abstract】 Compared with the results of tensile test, the feasibility of bend test used for the measurement of microstrain in metals was analysed and demonstrated in detail. Based on the test of microplastic deformation process in LD2, 1Cr18Ni9Ti and H62, the dimensional effect sources of error and the way of crror correction are discussed.更多还原
