摘要: Bulk anisotropic nanocrystalline SmCo5 magnets have been prepared by hot deformation method. The height reduction of the plays a key role in inducing crystallographic alignment magnet. Increase to 90% leads formation platelet shape grains perpendicular press direction; correspondingly c-axis texture and magnetic anisotropy were developed deformed magnets. coercivity increases first,and then decreases again with increase reduction. magnet 70% exhibits high over 5 T.
