Description

The possibility of using a synergetic approach for the description of stochastic nature of phase transformations in Pd-M-H systems is shown for earlier revealed nonmonotonic irregular phase transitions in a Pd-Er-H system. Microscopic and synergetic models of structural transformations are developed, and their stochastic character is revealed on relaxation of the hydrogen-saturated alloy within a time range of 102-104 h. The conditions of realization of these transformations are determined in the frameworks of Lorentz model

Abstract (Russian)

На примере анализа обнаруженных ранее немонотонных нерегулярных фазовых превращений в системе Pd-Er-H показана возможность использования синергетического подхода для описания стохастического характера указанных превращений в системах типа Pd-M-H. Построены микроскопическая и синергетическая модели структурных превращений, и выявлен их стохастический характер при релаксации насыщенного водородом сплава в интервале времени 102-104 ч. Определены условия реализации таких превращений в рамках модели Лоренца
