摘要：

The crystallization behavior and magnetic properties have been investigated in melt-spun Pr7Tb1Fe84.5Nb1.5B6 samples. A c-axis texture of 2:14:1 phase was observed in ribbons spun below 14 m/s. Samples spun above 40 m/s show an amorphous phase, which crystallizes into a TbCu7 structure before it transforms into the 2:14:1 phase. At higher temperatures, (Pr,Tb)(1+delta)Fe4B4 phase precipitates from the matrix, Optimum magnetic properties are found with coercivity H-c = 8.6 kOe and (BH)(max) = 17.3 MG Oe.
