| Abstract Scope |
The phase-field method has recently been applied to modeling additive manufacturing (AM) of metallic alloys. For example, it has been employed by a number of groups to model powder consolidation, gas pore evolution, dendrite morphology evolution, grain growth and solid-state transformations during AM. However, in order to develop the phase-field method as efficient and reliable ICME tool for AM, we have to overcome several challenges. These include (1) the huge amount of computational resource required for full-scale three-dimensional simulations under realistic AM processing conditions, (2) the lack of reliable materials data as input parameters and their uncertainty, (3) the difficulty to conduct parallel experiments to validate the predicted microstructure evolution, (4) the complexity involved in the coupling among different microstructure features at different spatial and time scales, and (5) the identification of uncertainty sources and their propagation during the microstructure simulations. |
