Additive Manufacturing processes such as Laser Engineered Net Shaping (LENS) have become popular alternatives to traditional alloy manufacturing methods due in part to the potential for greater microstructural control through variation in process parameters and materials. We explore the applicability of a Cellular Automata (CA) model for simulation of both nucleation and growth of dendritic grains under LENS solidification conditions. The model will account for both homogenous and heterogeneous nucleation sites, as well as multiple solid phases and various intra-grain solidification morphologies. The application of the model to various phase diagrams, solute compositions, and LENS process conditions will be discussed as a step in developing a microstructural trend prediction and alloy design tool.
