Extension of the martensite transformation temperature relation to larger alloying elements and contents

Abstract

A new relation for the Ms temperature prediction is proposed. The composition ranges covered by the new model are enlarged compared to the classical relations. This new relation is obtained from a data base of almost 1000 different compositions. The predictive ability of this new relation is compared to the classical ones. This work presents a new relation to predict the martensite start (Ms) temperature in steels. The composition ranges covered by the new model are enlarged compared to the classical relations, and includes new alloying elements such as V, Ti or Nb. This new relation is obtained from a data base of almost 1000 different compositions. The predictive ability of the Ms temperature is improved compared to the classical relation. © 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
