AbstractEffects of the distribution of rare-earth elements on 2: 14: 1-type Ce-based sintered magnet with same nominal composition were investigated by respectively doping Nd-Fe and Ce-Fe eutectic alloys. The coercivity and the thermal stability of the magnet doping Nd-Fe alloy revealed more excellent performance (H-i(c) = 12.19kOe, alpha = -0.1474%/degrees C, beta = -0.5129%/degrees C) than those of the magnet doping Ce-Fe alloy (H-i(c) = 10.13kOe, alpha = -0.1665%/degrees C, beta = -0.5271%/degrees C). The difference of the newly formed grain boundary phases and elemental enrichment variation of the matrix phase grain for the processed magnets were two major reasons of the coercivity discrepancy. Ce-based magnet with optimized structure was obtained and this method was promising to maximize the utilization of abundant rare-earth element Ce in 2:14:1-type magnet. (C) 2018 Elsevier B.V.
