Simple approaches for solidification and diffusive homogenisation

Abstract

Much of the current research through national and international, academic and industrial collaborations targets some of the great complexity exhibited by microstructural evolution in multicomponent systems such as steels. Such work clearly has an important role in the understanding and development of alloys, but it must be remembered that in many cases, simple approaches give sufficient answers and indeed are desirable for incorporation into macromodels where the progress of the microstructural evolution routine is interrogated a large number of times. Simple approaches for solidification and subsolidus homogenisation are presented for this purpose and validated against established models and experiment.
