Multi-phase-field法を用いた金属粉末積層造形モデリングの検討

抄録

Accurate prediction of the material microstructure formed by additive manufacturing (AM) is key to improving the properties of metal AM products. In this study, a model to simulate the material microstructure formed during the powder bed fusion AM is investigated. In the model, melting and solidification due to laser scanning, liquid flow in melt pool, and grain growth in solidified layer and substrate are modeled in an integrated manner using a multi-phase-field method.
