摘要：

It has been found that an addition of a large amount of refractory elements, especially vanadium, in combination with a proper amount of boron is very effective to enhance the coercivity of the sintered NdFeB permanent magnets. The magnet of Nd16Fe72V4Ba which has a coercivity as high as 1.38 MA/m consists of three phases, Nd2Fe14B, Nd-rich phase, and V2FeB2 instead of Nd1. 1 Fe4B4 which is contained in the conventional NdFeB magnets. © 1990 IEEE
