In this study we present a large scale numerical simulation of γ -γ microstructure evolution in Nibase superalloy using the multi-phase field method in three dimensions. We numerically simulated precipitation hardening heat treatment cycles. Large scale three dimensional simulations are necessary in order to get sufficient statistics for predicting the morphological evolution, average γ precipitate size, precipitates size distribution over time and ripening exponent for a given temperature and

The study is performed using the phase-field modelling library "OpenPhase" which is based on a multi-phase field multi-component model.
