本文研究了NdFeB烧结磁体吸放氢的动力学行为。在高于200/spl deg/C的温度下的氢化用于破碎富Nd相。Nd/sub 2/Fe/sub 14/B相的晶粒没有受到损伤。氢解吸分几个阶段进行，并在约400/spl deg/C下完成。>
The kinetics of the hydrogen absorption and desorption behaviour of a NdFeB sintered magnet is studied. Hydrogenation at temperatures above 200/spl deg/C is used to crumble the Nd-enriched phase. The grains of Nd/sub 2/Fe/sub 14/B phase remain undamaged. Hydrogen desorption occurs in several stages and is complete at approximately 400/spl deg/C. >
