Abstract

Microstructure and its mechanical properties at elevated temperatures are the major factor controlling the performance of Ni-base super-alloys. In this study we present a numerical simulation of microstructure evolution of Ni-base super alloy using multi-phase field method. The microstructure evolution during the heat treatment cycle is numerically simulated with our in-house software 'OpenPhase' which is based on a multi-phase field multi-component model [Steinbach et al., 1996; Steinbach, 2009]. We discuss on the coarsening kinetics, parameters influencing it and identify directions for future work.
