Abstract

This work presents a modelling approach for the simulation of the microstructure evolution during solution heat treatment in technical, multi component superalloys. This model is based on a theoretical approach and calclations. All calculations start with the simulation of solidification, as the as-cast microstructure is the starting condition to simulate the subsequent heat treatment. The model takes into account typical length scales, diffusion, morphological and constitutional aspects of the alloys. Simulations are performed for an alloy with several alloying elements. It is proposed that with the aid of the simulations optimised solution heat treatments can be derived.
