文摘The kinetic process of MmNi3. 55Co0. 75Mn0. 4Al0. 3 alloy absorbing hydrogen in αand α+βphases at the temperature range of 22￣ 60℃ has been studied. The results show that the kinetic process is controlled by chemical reaction in the α phase and the mechanism of hydrogenation kinetics is not affected by initial hydrogen pressure. In the α+β phase region,the speed of hydrogen absorption is controlled by hydrogen diffusion in the hydride.A reaction rate equation and apparent activation energy have been obtained.
