Abstract

Precipitation of γ′ particles from a disordered γ matrix in a Ni-Al alloy is studied. A continuum phase-field model is employed in three-dimension(3D). The focus is on the evolution of γ′ particle morphology and development of spatial correlations during coherent nucleation, growth and coarsening. The effect of lattice mismatch on the rate of coarsening is investigated. The results are compared with those obtained from two-dimension(2D) simulations.
