Features of the hydrogenation of titanium- and magnesium-base composite materials

The purpose of this work was a detailed study of the interaction with hydrogen of the titanium-alloy (magnesium-lithium) pseudoalloy and also investigation of the process of hydrogenation of pseudoalloys of titanium with intermetallides of magnesium (Mg-Ni, Mg-Cu, Mg-Y, Mg-La) traditionally used for adsorption of hydrogen. The hydrides were decomposed in heating to 1173/sup 0/K in vacuum. The temperature of the start of liberation of H/sub 2/ was recorded at the moment when the hydrogen pressure above the hydride reached 500 Pa. The structure of the specimens was studied on a Reichert optical microscope and on a JEM-U3 scanning electron microscope. The composition of the hydride phase was determined by x-ray diffraction.
