Anisotropic Nd-Fe-B powder made through hot-forming process is a promising material for high performance bonded magnet. It is important to clarify effects of various conditions in hot-deformation process on magnetic properties of anisotropic powder in order to improve them. In this study, we investigated effects of deformation temperature and strain on magnetic properties of anisotropic powder. The results showed that both of hot-deformation temperature and strain greatly influenced magnetic properties of the anisotropic powder. Consequently, the optimum temperature and strain condition to achieve the maximum hard magnetic properties were obtained. Anisotropic compression-molded bonded magnets made from hot-upset powder through the optimum condition were fabricated; the bonded magnet with the composition of Nd0.137Fe0.735Co0.067B0.055Ga0.006 showed the highest-class (BH)max value of 178 kJ/m3, on the other hand the bonded magnet with the composition of Nd0.130Dy0.016Fe0.726Co0.068B0.054Ga0.006 had not only high coercivity of 1.6 MA/m but high (BH)max of 138 kJ/m3.
