摘　　要：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 ribbons after precipitation hardening. （BH）max about by the adjustment of composition. However, the crystallographic texture is still preserved in the 86kJ/m^3 can be obtained in the Sm（Co, Fe, Cu, Zr）z ribbonsSm（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℃.
