Sm(CobalFeyCuxZrw)z ribbons have been prepared by melt spinning at a low wheel velocity followed by shorttime aging and slow cooling the as-spun ribbons from 850 to 400℃. It is found that the composition can significantly influence the degree of crystallographic texture of the ribbons. The 1:7 phase of the as-spun ribbons is segregated into 1:5 and 2:17 phases by the simple processing procedure. However, the crystallographic texture is still preserved in the ribbons after precipitation hardening. (BH)max about 86kJ/m3 can be obtained in the Sm(Co, Fe, Cu, Zr)z ribbons by the adjustment of composition.
