摘      要：Melt-spun Y_(16)Fe_(78)B_(6)ribbons were prepared by the melt-spinning technique with pure elements Y,Fe and Fe-B alloy n *** ribbons are mainly composed of Y_(2)Fe_(14)B,YFe_(2)andα-Fe *** phase appears at the wheel velocity of35 m·s^(-1).For the ribbons prepared at optimum wheel velocity and heat treatments,the coercivity,remanence and maximum energy product are239.5 kA·m^(-1),0.61 T and 32.7 kJ·m-3,*** an investigation of Henkel plots of ribbons,it is found that intergrain exchange coupling leads to the enhancement of *** coercivity mechanism of ribbons prepared at 35 m·s^(-1)is mainly controlled by inhomogeneous pinning of domain *** phase component and magnetic properties change with annealing temperature and *** optimum magnetic properties are obtained with the ribbon quenched at 35 m·s^(-1)and annealed at 700℃for10 min.
