摘要：

In the present work, the thermal properties and crystallization process and kinetics of the as-spun Pr6Fe78B16 are thoroughly investigated. The activation energies E-c(x) of crystallization for the Pr2Fe14B phase increase rapidly first and then increase slowly to a maximum value 440 kJ/mol at the crystallization value of 40%, while the E-c(x) of Fe3B phase is mostly lower at the stage of crystallization and then increases gradually with the increase of crystallization fraction. Meanwhile, the enhanced magnetic properties (H-cj, 215 kA/m; M-r, 116 A m(2)/kg; and (BH)(max), 73.9 kJ/m(3)) have been obtained for the alloy with the annealing temperature at 660 degrees C. The results of magnetization reversal behavior show that a stronger exchange-coupling interaction between the hard and soft phases can be obtained by the proper annealing temperature.
