Abstract Scope |
High accurate control of polycrystalline microstructure is key to produce high-performance Nd-Fe-B based permanent magnets [Scripta Mater., 67 (2012) 530-535]. This has been clarified by micromagnetic simulations considering microstructures [Mater. Trans., 57 (2016) 1221-1229.]. However, simulations for microstructure formation processes are very limited [J. Japan Inst. Met. Mater., 81 (2017) 43-48]. In this study, in order to develop a prototype model for microstructure prediction of Nd-Fe-B magnets, we investigate a multi-phase-field model to express the formation process of polycrystalline microstructure with high anisotropy and with grain boundary phase. Moreover, we show some simulation examples of grain growth for a binary alloy. |
