Results are provided for a study of the effect of thermal cycling treatment on the structure and properties of ferritic-austenitic steel welded heat-affected zone metal. Optimum thermal cycling regimes are determined. It is shown that an increase in heat-affected zone impact strength with thermal cycling is due to fragmentation of structural components, redistribution of alloying elements between phases, and excess phase amount and morphology.
