摘 要：The ribbons of NdFeB/α-Fe composite alloy were prepared by melt spinning and post crystallizing technique.The element distri-butions and phase component of both surfaces of as-spun ribbons were measured by energy dispersive spectrometry （EDS） and X-ray diffrac-tion （XRD）.Because of the centrifugation,a segregation of B,Fe,and Nd concentrations was observed at the cross section.After crystallizing annealing,the element concentration segregation still existed in the as-crystallized ribbons.Due to the segregation of B,Fe,and Nd,the B-rich phase was observed near the wheel side surface.The B-rich phase may deteriorate the magnetic property of NdFeB/α-Fe composite alloy.
