标准摘要
[中文适用范围]： 本文件规定了使用电子背散射衍射 (EBSD) 定量分析钢中奥氏体的程序。 本文件主要适用于低中碳钢、低中碳合金钢。 本文件用于分析晶粒尺寸大于 50 nm 的奥氏体。 该方法不用于定量晶粒尺寸小于50 nm的奥氏体，这会显着影响分析结果的准确性。 注 1：尺寸限制很大程度上取决于仪器和仪器操作参数。 注 2：尺寸限值是可检测奥氏体的最小晶粒尺寸。 [外文原描述]： 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.
