A comprehensive three-dimensional (3D) stochastic model for simulating the evolution of dendritic crystals during the solidification of binary alloys was developed. The model includes time-dependent computations for temperature distribution, solute redistribution in the liquid and solid phases, curvature, and growth anisotropy. 3D mesoscopic computations at the dendrite tip length scale were performed to simulate the evolution of columnar and equiaxed dendritic morphologies and compared then with predictions obtained with 2D mesoscopic computations.
