| 中文摘要 | The effect of additive C on characterization of crystalline texture and magnetic properties of anisotropic melt-spun Sm(CoZr)(7) alloy has been investigated. A few percent of C addition was found to not only significantly enhance the coercivity of the ribbons but also affect the characterization of crystalline texture. The easy-magnetization c axis is changed from parallel to the ribbon plane for SmCo6.5Zr0.5 ribbons, to normal to the ribbon plane for the SmCo6.5Zr0.5C0.5 one. Maximum energy product of SmCo6.5Zr0.5C0.5 ribbons prepared at 5 m/s, pulse magnetized to 5 T and measured normal or parallel to the ribbon plane is 8.6MGOe or 3.2MGOe, respectively. The domain structure was studied by magnetic-force microscope. A strip-shaped domain can be observed on the surface of the SmCo6.5Zr0.5 ribbons and the walls lie straight and parallel. For C-doped ribbons, the domain walls form a maze domain pattern of grains with c axis normal to the ribbon plane. Scanning electron micrography analysis showed that a dendrite structure was present in the SmCoZr ribbon surface. C addition leads to the diminishing of the above dendrite and the grains become equiaxial, The characterization of crystalline texture in C-free and C-doped ribbons has been correlated with their microstructure. |
