采用单辊快淬法制备了Nd-Fe-Co-Cu-Nb-B系合金快淬薄带，研究了合金成分、快淬速度和热处理对合金磁性能的影响。最佳制备工艺条件为：成分为Nd5Fe71Co5Cu0.5Nb1B17.5，轮速为20 m/s，退火温度为650°C，退火时间为10 min，氩气保护。磁性能：Jr = 1.175 T，HcJ = 342.6 kA / m，HcB = 307.6 kA/ m，（BH）max= 114.8 kJ/ m3，α（Br）= -0.056%/°C，β（HcJ）= -0.354%/°C。
Melt-spun ribbons of Nd-Fe-Co-Cu-Nb-B system alloys were prepared by the single-roller rapid-quenching method, and the effects of the composition, wheel velocity, and heat treatment on the magnetic properties were investigated. The optimum preparation conditions and some properties are as follows: composition, Nd5Fe71Co5Cu0.5Nb1B17.5; wheel velocity, 20 m/s; annealing conditions, 650°C ×10min in Ar atmosphere; magnetic propeties, Jr = 1.175 T, HcJ = 342.6 kA / m, HcB = 307.6 kA / m, (BH)max=1 14.8 kJ/ m3, α(Br) = -0.056%/°C, β(HcJ) = -0.354%/°C.
