主 题：Co-Zr Alloys Co5Zr Phase Coercivity Melt-Spun Permanent Magnets
摘 要：Based on X-ray diffraction, microscopic and magnetic analysis, the structure and magnetic properties of Co77Zr18W5 melt-spun ribbons were studied in this paper. A new element to stabilize the metastable Co5Zr phase was found and the coercivity observed in Co-Zr alloys can be obviously enhanced by proper tungsten substitution. The Curie temperature of Co77Zr18W5 ribbons is 475℃ which suggests that W doped Co-Zr alloys may become an attractive candidate perma- nent magnets for practical applications in high temperature. Annealing of the Co77Zr18W5 ribbons results in a decrease of the coercivity which confirmed that the hard magnetic phase is Co5Zr phase in 77Zr18W5 melt-spun ribbons.
