金属材料布氏硬度测量结果不确定度的评定

Evaluation of Measurement Uncertainty in Brinell Hardness Test for Metallic Materials

笔者对金属材料布氏硬度试验中的测量不确定度来源进行了分析,而且借助于KB3000BVRZ全自动硬度试验机对布氏硬度测量结果的不确定度进行了详细的评定,最终给出了扩展不确定度。

The sources of measurement uncertainty in Brinell hardness testing for metallic materials were analyzed. The measurement uncertainty of Brinell hardness was detailedly evaluated by using KB3000BVRZ-automatical hardness tester,and the expanded uncertainty obtained.
