金属材料拉伸试验检测结果测量不确定度的评定

Detection of Uncertainty of Result Evaluation of Metallic Materials in Tensile Test

金属材料的力学性质主要取决于所用材料本身的组织结构以及化学成分等。在金属材料力学性能的试验当中,影响金属材料拉伸试验检测结构因素很多,相同材料经过不一样的拉伸试验就能反映出不一样的性能指标。

The mechanical properties of metal materials mainly depend on the organizational structure and chemical composition of materials used. In the test of the mechanical properties of metallic materials, a lot of factors can affect the tensile test detection structure of metallic materials. The same material can reflect the different performance indicators after different tensile tests.
