Description

The gist of this method is the use of hydrides of transition metals as starting materials for synthesis of alloys and intermetallides. At heating a compacted powder mixture of two or more hydrides (or hydrides and metals) and hydrogen removal at a temperature slightly higher than that for hydrides dissociation, the strong, nonporous alloy or intermetallide is formed. The objective of the work was to identify the basic regularities, which affect the mechanism of formation in hydride cycle of tri-aluminides in the xTiH2-(1-x)ZrH2-3Al. The results of performed studies revealed the ratio of ZrH2, TiH2 and Al powders, the pressure at compacting, the temperature and the rate of heating influencing the characteristics of formed aluminides
