Abstract
A major challenge in additive manufacturing is to relate process parameters and microstructure. This relation can be explored with phase field method coupled to a larger scale heat transfer model. Phase field method is the state-of-the-art method to simulate the kinetics of solidification, including the development of microstructural features including grain morphology, solute distribution, and formation of metastable phases. In this work we study the selective laser melting (SLM) of a nickel based superalloy. Taking into account the major segregating chemical elements, the solidification patterns are modeled using the phase field method. The large scale heat transfer model is used to estimate the temperature distribution and history, specifically thermal gradients and cooling rates.
