Description:
To study the behavior of solid dendritic growth involving a cubic-to-cubic coherent precipitate transformation, a phase-field model incorporating the coherent elastic strain energy base on a solidification model, is proposed and a parallel multigrid scheme is developed to solve the elasticity problem in the model. Numerical tests in 2D demonstrate that the algorithm could shorten the elapsed time by two order of magnitude, making it feasible to carry out investigation on the underlying physics of the phase transformation. The simulation results show that the appearance of the elastic energy promotes precipitate’s dendritic growth with preferential directions of . With the interfacial energy anisotropy is considered, the ultimate morphology of precipitate is highly dependent on competition between anisotropy of the elastic energy and the interface energy.
