Starting with the ingot with a nominal stoichiometric composition of SmCo9.8, the nanocrystalline bulk with ultrafine nanograin structure was prepared by a route combing ball milling and spark plasma sintering. The phase formation, microstructure, crystal lattice characteristics, and magnetic performance of the nanocrystalline SmCo9.8 alloy were investigated. The TbCu7-type solid solution of the SmCo9.8 composition was obtained, and the crystal structure of the nanocrystalline 1:9.8 H was constructed. The magnetic features were disclosed through nanostructuring to obtain the single metastable 1:9.8 H. It was found that the nanocrystalline SmCo9.8 alloy has high saturation magnetization and Curie temperature. The study presents a new understanding of the nanoscale-stabilized TbCu7-type solid solution of the SmCo9.8 composition and may promote the development of SmCo9.8-type alloys as candidates for the high-temperature permanent magnets, based on the coercivity improvement.
