摘要
Our electron microscopic studies of as cast Sm(Co, Fe, Cu, Zr)9 Magnets revealed a “new” hexagonal phase of the type Sm2(Co, Fe, Cu, Zr)17 with crystal lattice parameters of a=0.84 nm and c=3.2 nm. After a solid solution treatment only rhombohedral (3R) and hexagonal (2H) grains are found. After an additional annealing treatment at 800oC grains with a microcellular precipitation structure similar to the one found in sm(Co, Fe, CU, zr)7.5 magnets occur. Besides this, in the as cast and after aged samples also other, partly unidentified Cu- or (Co, Fe)-enriched phases were detected. © 1990 IEEE
