| heal.abstract | High coercivity, the highest for Cu-free 2: 17 Sm-Co ribbons, has been obtained in as-spun (H-c = 21.1 kOe) and short time annealed (H-c = 23.2 kOe) samples of Sm(CobalFezZryBx)(7.5) alloys, with varying B, Zr, and Fe content (x = 0-0.06, y = 0-0.16, z = 0.08-0.3) and wheel speed. In as-spun samples, the TbCu7 type structure and in annealed samples the Th2Zn17 and CaCu5 type structures is observed, plus fee Co as minority phase is observed. Reduced remanence (M-r/M-s) is higher than 0.7. High-temperature magnetic measurements show very good stability above 300 degreesC with coercive field as high as 5.2 kOe at 330 degreesC. For annealed Sm(CobalFe0.3Zr0.02B0.04)(7.5), very good loop squareness and high maximum energy product of 10.7 MGOe have been obtained. Increasing Zr content results in less uniform microstructure of annealed ribbons. | en |
