The second phase of the research proposal aims to develop the Sm-Fe-V phase diagram, which will enable the determination of the equilibrium between the hard magnetic SmFe12 phase and the liquid phase. This equilibrium is essential for achieving magnetic isolation of hard magnetic grains in the microstructure, which is a key factor in obtaining high coercivity. In pursuit of this goal, we conducted a systematic investigation of the magnetic, microstructure, and crystallographic properties of anisotropic SmxFebalV20 for for 5.7<x<10 and 0<y<30. By combining these results with a computationally modeled Sm-Fe-V phase diagram, we can uncover the relationship between the intergranular phases and the coercivity.
