On deformation behavior of Fe-Mn based structural alloys

Abstract

This article is a literature review of recent advances in novel Fe-Mn based alloys, drawing specific examples on Hadfield and TWIP steels, and high entropy and shape memory alloys. A critical discussion of these alloys merits. a uniform treatment owing to their remarkable mechanical attributes, i.e. a substantial combination of strength and ductility. It is interesting to note that their microscopic deformation mechanism also shares commonality in terms of twinning-dominated'straining in addition to slip-based plasticity. In the past two decades alone, a synergy of materials science and mechanics based studies has significantly helped uncover the microstructural origin, effects of alloying etc. therein. In this paper, we discourse elaborately on the reported microstructure-property correlations. By surveying these developments, we point out how the current knowledgebase can pave the way for strategizing future materials advancements as well as expanding applications. (C) 2017 Elsevier B.V.
