摘 要：<正> The microstructures of melt-spun Nd135-Fe81.74B4.76 ribbons have been investigated bymeans of X-ray diffraction,Mossbauerspectroscopy and HREM.Experimental resultsshow that optimal magnetic properties of the bond-ed magnet can be obtained by melt-spun alloys atwheel velocity of 24m/s,the microstructure ofwhich was single phase Nd2Fe14B crystallites,andno other phases,such as Nd-rich,B-rich or x-Fephase,were present.It is considered that the highintrinsic coercivity iHc can be attributed to the sin-gle-domain behaviour of Nd2Fe14B crystallitephase.
