摘要：
Sm(Co0.6Fe0.27Cu0.1Zr0.03)(7.5) ribbons were prepared by melt-spun method. The results showed that the remnant magnetization M-r and intrinsic coercivity H-ci had a rapid increase when the heating rate increased from 5 to 10 degrees C/min. But the increase of M-r and H-ci were observed to be very little when the heating rate was further increased to 20 degrees C/min. 10 degrees C/min was the critical heating rate for obtaining high magnetic properties. The maximum values of M-r and H-ci reached 0.70 T and 780.1 kA/m when the annealing temperature and annealing time were optimized to be 800 degrees C and 1 h, respectively. Proper second-step heat treatment could suppress the decrease of H-ci when the cooling rate increased from 0.7 to 5 degrees C/min, which could reduce the cooling time effectively.
