摘要：

Magnetic properties and microstructure were investigated in Sm17.24Co66.20Cu8.28Fe8.28 ribbons melt-spun at different wheel speeds of 5, 15, 30, 40 and 50 m/s. X-ray diffraction studies revealed that the ribbons melt-spun at lower wheel speed (<15 m/s) were comprised of three phases viz. SmCo7, Sm2Co7 and SmCo5, while higher wheel speed ribbons exhibited single phase SmCo5. The coercivity was found to increase with increase of the wheel speed. A high coercivity of similar to 33 kOe was obtained in ribbon prepared at 50 m/s. (C) 2007 Elsevier B.V. All rights reserved.
