Abstract: A non-evaporable getter alloy is provided which can be used in a process for the sorption of gas from a closed vessel comprising the step of:introducing into the vessel a non-evaporable ternary gettering alloy whose composition in weight percent when plotted on a ternary composition diagram in weight percent Zr, weight percent V and weight percent Fe lies with a polygon having as its corners the points defined by:(a) 75% Zr-20% V-5% Fe(b) 45% Zr-20% V-35% Fe(c) 45% Zr-50% V-5% Fesuch alloys can sorb water vapor without the release of H.sub.2 between 200.degree.-350.degree. C. and can be used in a wide temperature range for the sorption of other gases. They can also be activated in short times at relatively low temperatures, to be used as a getter at room temperature.

Abstract: This invention relates to a method for the production of non-evaporable ternary gettering alloys of the type Zr-M.sub.1 -M.sub.2 in which M.sub.1 is a metal chosen from the group comprising vanadium and niobium, and in which M.sub.2 is a metal chosen from the group comprising iron and nickel.
