FIELD: metallurgy.
SUBSTANCE: invention refers to non evaporating gas absorbing alloys actuated at relatively low temperatures and capable to trap hydrogen. The invention can be implemented at fabrication of thermal flasks, solar collectors, lamps of discharge voltage, and generating X-ray tubes. The alloy has the following composition, wt %: Zr 50-80, Y 10-20, M 5-40, where M is chosen from Al, Fe, Cr, Mn, V or mixtures of these elements. The region of alloy contents is limited with polygon determined with points on triple diagram, wt %: a) Zr 50 % - Y 10 % - M 40 %; b) Zr 50 % - Y 20 % - M 30 %; c) Zr 75 % - Y 20 % - M 5 %; d) Zr 80 % - Y 15 % - M 5 %; e) Zr 80 % - Y 10 % - M 10 %.
EFFECT: improved characteristics of equilibrium pressure of hydrogen and temperature of activation relative to known materials.
