Spatial Aspects of Martensite

Abstract

This work re-examines the martensite transformation in FeNiC, FeNiMn, and high-C steels using the microstructural path concept adapted to the uniqueness of martensite. The analysis of the microstructural path and the developed formalisms support the view that strain accommodation underlies the development of the spatial aspects of the transformation in the alloys considered. The partitioning of the austenite grains and the martensite burst are entailed by the elastic propagation of the midribs. In addition, we found agreement of the empirical equations used in previous works and the microstructural path models now described.[PUBLICATION ABSTRACT]
