摘 要：The aim of the present work was to study the effect of austenite grain size （AGS） on the martensite formation in a high-manganese twinning-induced plasticity （TWIP） steel. The results of a quantitative microstructural characterization of the steel by the whole X-ray pattern fitting Rietveld software, materials analysis using diffraction （MAUD）, indicated that the volume fraction of α bcc-martensite increases with increasing AGS. However, the value of the stacking fault probability （P sf ） does not show a large variation for samples with different values of AGS under water-quenching conditions.
