摘要
对17个金属材料平均晶粒度测定的相关标准方法中的晶粒度定义、图谱比较法、面积法、截线法以及准确度5个方面进行了比对分析。通过比对分析,明确了标准之间的一致性、差异性以及存在的缺陷,方便检验员对标准的选择和使用,有利于标准化工作的持续改进。
Five aspects of 17 standards for determining average grain size of metallic materials were compared and analyzed,including the definitions of the grain size,the chart comparison procedure,the planimetric procedure,the intercept procedure,and the accuracy. The consistencies,differences and shortcomings among these standards were clarified through comparative analysis,and the results were conducive to the selecting and using of the standards by metallographers and the continual improvement of standardization work.
