Interaction of magnesium alloys with hydroge

摘要

Interaction with hydrogen of intermetallics, solid solutions and multiphase alloys in systems Mg-Ln (Ln = La, Ce, Er, Yb), Mg-Ca-M (M = Al, Zn, Ce, Cu, Ni), Mg-Ln-M (Ln = La, Ce, Sc, Y, Mm; M = Al, Ni) was investigated. The dependece of hydriding parameters of alloys on their phase composition and mcirostructure was established. On the basis of kinetic measurements the values of activation energy of hydriding-dehydriding in multi-component Mg-based sytstems was calcualted and a model for reaction of Mg hydride formation in presence of rare-earth metals was proposed. The stability of hydrogen adsorption in pure and commercial hydrogen atmosphere was studed.
