摘要
研究了Nd Fe B合金的氢化 歧化物的脱氢过程的特点 ,通过对原料合金、氢化 歧化物和脱氢合成材料的微观结构、X射线衍射图和磁性能的对比研究 ,建立了Nd Fe B氢化 歧化物脱氢再合成Nd Fe B型硬磁材料的机理。
The characteristics of the desorption process of the hydrogenation disproportionation product of NdFeB alloy were investigated. Nd Fe B alloy was melted in a vacuum mild frequency induction furnace. The sample was prepared by a hydrogenation disproportionation desorption recombination process. The mechanism of the recombination Nd 2Fe 14 B type hard magnetic material by a desorption of hydrogenation disproportionation product of NdFeB alloy was established by the comparison of the microstructures, X-ray diffraction patterns and magnetic properties.
