英文名称：Microbeam analysis — Electron backscatter diffraction — Quantitative determination of austenite in steel
发布日期：2022-04
标准范围
This document specifies procedures for quantitative analysis of austenite in steel using electron backscatter diffraction (EBSD). This document is mainly applied in low and medium carbon steels, low and medium carbon alloy steels.
This document is used to analyse austenite with grain size larger than 50 nm. This method is not used to quantify austenite with grain size smaller than 50 nm, which can significantly affect the accuracy of the analysis results.
NOTE 1 The size limit is strongly dependent both on the instrument and the instrument operating parameters.
NOTE 2 The size limit is the minimum grain size of the detectable austenite.
