| Popis: | The kinetics of the hydrogen induced direct phase transformation in Y2Fe17 magnetic alloy has been analysed within the framework of Kolmogorov’s kinetic model. It is established that the transformation can be classified as a diffusion-controlled transformation, which occurs by a mechanism of nucleation and growth with a decreasing nucleation rate of new phases, namely α-Fe and YH2. A kinetic equation has been obtained that well describes the isothermal kinetic curves of the phase transformation in Y2Fe17 as a function of the transformation temperature. |
