| Abstract Scope |
Sm2Fe17Nx is an iron based rare earth intermetallic compound, that has a great potential for use as high-performance permanent magnet owing to its excellent intrinsic magnetic properties. However, sintering of powders into bulk sintered Sm-Fe-N magnet requires a suitable low melting metal binder such as Sm-Cu and Sm-Ni. In this work, the microstructure evolution, phase formation and magnetic properties of Sm60Ni40 alloy both in as-cast and annealed (903 K for 100 h) conditions were investigated. The high temperature stable Sm3Ni2 phase was stabilized at room temperature and crystal structure was determined to be monoclinic. Correspondingly, the Curie temperature of Sm3Ni2 phase was measured to be 110 K, exhibiting high magnetocrystalline anisotropy as evident from the high coercive field of 3 T. |
