| 中文摘要 | Amorphous (Nd,Pr)13Fe80NblB6 ribbons were crystallized at 670-730℃ for 5-25 min to study the effects of isothermal crystallization on their behavior and magnetic propefties．XRD results indicate that the isothermal incubation time is 12,5,and less than 5 min at 670，700，and 730℃,respectively．High coercivities，with the maximuln value of jHc=1616 kA／m at 700℃ for 19 min，measured by a physical property measulement system,are obtained in the crystallized ribbons．This is mainly attributed to the addition of Pr and Nb,because Pr2Fel4B has a higher anisoutropic field than Nd2Fel4B，and Nb enriched in the grain boundary regiom can not only reduce the exchange-coupling effects among hard grains，but also impede grain growth during the crystallization process．In addition,it should also be relagted to the characteristics of the furnance that the authors designed． |
