Influence of heat treatment on fracture and magnetic properties of radially oriented Sm2Co17 permanent magnets TIAN Jian-jun(田建军), QU Xuan-hui(曲选辉), ZHANG Shen-gen(张深根), A. FARID, TAO Si-wu(陶斯武... and aging treatment of radially oriented Sm2Co17 ring magnets were investigated. The results indicate that the ring magnets have obvious anisotropy of thermal expansion, which easily leads to the splits......
