摘要：
Effects of Ti and C addition on crystallization process and magnetic properties of NdPrFeB thick ribbons were investigated. The results show that doping of Ti suppresses the formation of (Nd,Pr)(2)Fe23B3 metastable phase and refines grains of the alloys and increases coercivity significantly. In the case of co-addition of Ti and C, the coercivity is decreased but the remanence is enhanced with increasing of C content. The magnetic properties of J(r)=0.88 T, H-cj=618 kA/m and (BH)(max)=109.8 kJ/m(3) are achieved in the (Nd0.4Pr0.6)(9)Fe72Ti4B11C4 ribbons after optimal annealing.
