Microstructure and magnetic properties of bulk Nd2Fe14B/α-Fe nano-composite prepared by chemical vapor deposition
Source abstract
Abstract
Abstract The chemical vapor deposition (CVD) method was adopted to coat soft α-Fe layer on the quenched Nd 13.5 Fe 80 Ga 0.5 B 6 ribbons. Microstructure and magnetic properties of the coated ribbons, isotropic and anisotropic Nd 2 Fe 14 B/α-Fe nano-composites were examined by means of X-ray diffraction, back-scattered electron scanning electron microscopy, field emission scanning electron microscopy and a vibrating sample magnetometer. The results showed that the CVD method was effective to introduce soft phase into the nano-composites. The microstructure and magnetic properties of isotropic/anisotropic Nd 2 Fe 14 B/α-Fe nano-composites would improve if the NdFeB ribbons were deposited with appropriate amount of soft phases. Excessive soft phase would weaken the magnetostatic coupling between soft/hard grains and deteriorate the alignment of Nd 2 Fe 14 B grains.
