Notes:
Sm(CoFeCuZr)z commercial magnets are manufactured by powder metallurgytechniques. Microstructural investigations of Sm(CoFeCuZr)z magnets have shown that, increasingthe Zr content, some impurity phases may appear. An alloy with composition (at%): 60.5% Co –15.5% Fe – 11.5% Zr - 8.5% Sm - 4% Cu, homogenized at 1050oC, was investigated. Three mainphases were identified: rhombohedral 1:3 (ZrSm)1(CoFeCu)3, hexagonal 1:7 (SmZr)1(CoFeCu)7 andcubic 6:23 (Zr)6(CoFe)23. Knowledge of possible phases present in 2:17-type magnets allows abetter understanding of the nanocrystalline microstructure responsible for high coercivity of thesemagnets
