The quasi-binary ZrFe2ZrMo2 system is an example of a fairly complex metal system with the structure of the Laves phases. Both ZrFe2 and ZrMo2 intermetallic compounds crystallize in the cubic type lambda(2)-MgCu2, for intermediate compositions ZrFe2-xMox an extended region with a hexagonal type of structure lambda(1)-MgZn2 is detected, and also two-phase regions (lambda(1) + lambda(2)). The formation of hydrides in this system under conditions of various pressures and temperatures was investigated in a number of works. In this paper, an attempt was made to summarize all previously obtained results. (C) 2019 Hydrogen Energy Publications LLC. Published by Elsevier Ltd. All rights reserved.
