Abstract :
After homogenization, and subsequent nitrogenation, melt-spun Sm 2Fe17Nx shows high values of coercivity up to 2 T. The coercivity is further increased to 2.9 T by applying the Zn-bonding technique. Densities up to 6.7 g/cm3 can be achieved by hot isostatic pressing (HIP). After HIP, however, the Zn-bonded samples show a deterioration in the shape of the demagnetization curves, which is due to the formation of α-Fe, as indicated by X-ray diffractometry
