Abstract Scope |
Powder bed fusion (PBF) additive manufacturing can fabricate complex productions in a layer-by-layer manner. The process includes the melting and solidification of power particles by an electron beam. Therefore, highly accurate prediction of material microstructures and defects formed during the process is essential. In this study, we develop a numerical framework to predict microstructural evolutions formed during the PBF of a metallic alloy. Here, we couple the multi-phase-field models for solid phase sintering and polycrystalline solidification with liquid flow and solid motion to express power particles, melting of particles and substrate material, solidification, and liquid flow. |
