Precipitation Reactions in 3Cr1.5Mo Power Plant Steel

Nobuhiro Fujita and H. K. D. H. Bhadeshia

Abstract

A method has recently been developed to estimate the speed with which precipitation reactions occur in power plant steels. It is based on Avrami theory but with an adaptation that allows the treatment of simultaneous reactions. A number of approximations and inconsistencies in the theory have been eliminated in the present work. The modified theory is shown to successfullly predict new experimental data on 3Cr1.5Mo steel.
