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% Fe such 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.
