中文名称: 评估金相学部分中观测到的最大晶粒(ALA粒径)的试验方法 | 英文名称:Standard Test Methods for Estimating the Largest Grain Observed in a Metallographic Section (ALA Grain Size) |
中标分类:A42 | ICS分类:19.120 | 标准分类编号:AS | 页数:6 |
发布日期: | 实施日期:1999-04-10 | 作废日期: | 被替代标准: | 代替标准:ASTM E930-1999 | 引用标准:ASTM E1181;ASTM E112;ASTM E3;ASTM E407;ASTM E7 | 采用标准: | 起草单位: | 归口单位: |
标引依据: | 补充修订: | 备注: | 范围:1.1 These test methods describe simple manual procedures for measuring the size of the largest grain cross-section observed on a metallographically prepared plane section.1.2 These test methods shall only be valid for microstructures containing outlier coarse grains, where their population is too sparse for grain size determination by Test Methods E 112.1.3 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
