All heat treatments including thermochemical heat treatments give rise to residual stresses in steel. A number of computer models have been developed for calculating temperature and phase distributions as well as residual macrostresses. They are implemented in several commercial codes which are listed. To some extent it is now possible to tailor make residual stress profiles by controlling process parameters. In this paper an overview of the state of the art of modeling is made for martensitic hardening nitriding and laser cladding. The importance of being able to predict residual microstresses in all phases in multiphase structures is emphasised and some examples are given. It is concluded that much work remains to be done until it has reach the same maturity as the modling of macrostresses. Professor J. B. Cohen has made great contributions in this field.
