Abstract

A solution of hydrogen in the AB2 intermetallic compound with a C-15 structure is considered. The ordering of hydrogen atoms is investigated, which consists in forming their unequal distribution among the sub-lattices of the A2B2 interstices. It is demonstrated on the basis of qualitative analysis and numerical calculations that, in HfV2Dx compounds, the evolution of the redistribution of the interstitial atoms and their low-temperature order can be different depending on the hydrogen content in the solution and the energy parameter of the system p≡V 2/V 1.
