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 applies to analyze austenite with grain size larger than 50 nm. This method is not applicable to quantify austenite with grain size smaller than 50 nm, which could significantly affect the accuracy of the analysis results.
The size limit is strongly dependent both on the instrument and the instrument operating parameters.
The size limit is the minimum grain size of the detectable austenite.
