Effect of composition on the crystallographic texture and magnetic properties of the Sm(Co,Fe,Cu,Zr)_z ribbons prepared by simple processing

Sm(Co_\rm balFe_yCu_xZr_w)_z ribbons have been prepared by melt spinning at a low wheel velocity followed by short-time 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)_\rm max about 86kJ/m^3 can be obtained in the Sm(Co, Fe, Cu, Zr)_z ribbons by the adjustment of composition.
