Prediction of martensite start temperature of power plant
steels
T. Cool and H. K. D. H. Bhadeshia
Abstract
Many essential properties of iron alloys depend on what actually happens when Steels used in the construction of modern power plant contain
relatively large concentrations of alloying elements. The
martensite start temperature of such steels is important during
fabrication, and can not be estimated using conventional
empirical methods. It is demonstrated in the present paper that
a recent theory due to Ghosh and Olson can be applied to
predict both published and new experimental data on the
martensite transformation temperatures of power plant steels.
However, the method should not be used in circumstances where
the steels contain delta ferrite or undissolved carbides before
transformation.
