1 Scope
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.
