Abstract

We present a phase field theory for the nucleation and growth of one and two-phase crystals solidifying with different crystallographic orientations in binary alloys. The accuracy of the model is tested for crystal nucleation in single-component systems. it is shown that without adjustable parameters the height of nucleation barrier is predicted with a reasonable accuracy. The kinectics of primary soldification is investigated as a function of model parameters under equiaxial conditions. Finally, we study the formation of polycrystalline growth morphologies (disordered dendrites, spherulites, fractallike aggregates).
