There has been investigated kinetics of growth of new phases during hydrogen-induced direct and reverse phase transformation in Y2Fe17 alloy. It is shown that evolution of these phase transformations decrease with temperature transformation decreasing. It was determined that these phase transformations proceed by mechanism of nucleation and growth. It was built isothermal kinetic diagrams of both the direct and reverse phase transformations and established the activation energy values for these hydrogen-induced phase transformations.
Исследована кинетика роста новых фаз в ходе индуцированных водородом прямого и обратного фазовых превращений в сплаве Y2Fe17. Показано, что развитие как прямого, так и обратного фазовых превращений замедляется с понижением температуры обработки. Построены изотермические кинетические диаграммы прямого и обратного фазового превращений. Установлено, что данные превращения протекают по механизму зарождения и роста, рассчитаны значения энергии их активации.
