Abstract

The microstructural heterogeneities in steels may have different origins. The tendency in industry to decrease the total amount of reduction during hot working decreases the possibilities of applying approaches based on “thermo-mechanical homogenization”. In this situation, alternative approaches need to be evaluated to reduce the heterogeneities present in the initial microstructure and, simultaneously, to avoid the possibility of inducing additional heterogeneities during processing. This paper analyzes the relevance of several processing parameters in different cases.
