Experimental Examination of the Validity of the Model for Predicting M_s, Temperature for Martensitic Stainless Steels

Abstract

Comparisons between the experimentally measured M_s and the calculated M_s temperatures for eleven martensitic stainless steels were performed on the basis of conventional models.
Empirical formulae for the calculation of M_s temperature do not show enough ability to predict the M_s temperature of all martensitic stainless steels, i.e. available alloying elements and their composition ranges are restricted. While, the Ghosh and Olson model for the prediction of M_s temperature is shown to be reasonably good in estimating the M_s temperature for martensitic stainless steels except some conditions.
