| heal.abstract | Single-phase rhombohedral Sm-2(CobalFe0.2My)(17) B-x with M = Cr or Mn substituting for Co have been prepared and the influence of transition metals on crystal structure, anisotropy field, and Curie temperature, is examined. Sm2Co17 as-cast bulk sample has the 2: 17 hexagonal structure (type Th2Ni17), while boron addition stabilizes the 2: 17 rhombohedral structure (type Th2Zn17). Anisotropy field for Cr-doped as-cast sample is 74 kOe. Secondary phases of fcc-Co or Fe-Co are observed in some cases. A Cr-doped sample with y = 0.1 after annealing at 1190 degreesC for 26 h is single phase. Curie temperatures of as-cast samples vary from similar to849 degreesC to similar to687 degreesC depending on the composition. Mechanical alloying and melt spinning were used to develop coercivity. As-spun ribbons at 53 m/s with Cr present a nanocomposite structure with H-c = 5.2 kOe. Samples with Mn have a coercive field close to 0.4 kOe. Scanning electron microscopy studies-show different microstructure for Mn and Cr substituted ribbon samples. | en |
