Abstract

Phase constitutions of Fe-(20-30)wt%Mn-(0-10)wt%AI-C alloys have been investigated by electron probe microanalysis and transmission electron microscopy. The phase relations between austenite and perovskite carbide, (Fe, Mn)3AIC in the temperature range of 900-1 200°C have been carefully examined. An L1₂-type ordered structure, which was reported to be formed in rapidly solidified alloys as a metastable phase has not been detected in specimens aged at temperatures above 600°C.
