Microbeam analysis - Electron backscatter diffraction - Quantitative determination of austenite in steel

NEN-ISO 23749 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 analyze 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.
