Abstract

The present paper deals with the development of modules for the simulation of microstructure changes during thermal cycling indicating a combination of precipitation and dissolution of precipitates. A Monte Carlo simulation technique based on the Potts model was utilized. Nucleation sites of precipitates were randomly generated both on grain boundaries and in grains. The ratio of the growth rates of the two different precipitates was revealed as an important factor that determines the process of microstructure evolution. Thermal cycling resulted in grain refinement by the division of phase-boundaries that were formed by the precipitation. The refined microstructure after thermal cycling was similar to that observed in a Cu-Be alloy which shows discontinuous precipitation.
