Atomic density function modeling of microstructure evolution in Ni3−xFex alloys
2014
Abstract The kinetics of the microstructure evolution of Ni 3− x Fe x alloys is studied using numerical simulations based on the microscopic diffusion equation. In particular, the influence of the magnetic interactions on the morphological evolution and coarsening kinetics of ordered L 1 2 precipitates in a fcc disordered matrix is investigated. It is shown, that magnetic interactions increase the width of the miscibility gap and stabilize the L 1 2 ordered phase. The simulated microstructures agree with the experimental data.
