Modelling of Phase Transformations in Steel Weld Metal

H. K. D. H. Bhadeshia

Abstract

This paper deals with some of the latest issues in the modelling of steel weld microstructures, building on work already published in the open literature. The key factors reviewed include the nature of acicular ferrite (a most desirable phase), the formation of austenite in the heat-affected zone and finally, the tempering reactions in welds which are post-weld heat treated for service at elevated temperatures.
