Non-evaporable ternary gettering alloy, particularly for the sorption of water and water vapor in nuclear reactor fuel elements

摘要

The scope of the present invention is the provision of a non-evaporable gettering ternary alloy particularly for the sorption of water and water vapor in nuclear reactor fuel elements. The ternary gettering alloy has a composition which when plotted on a ternary composition diagram in weight percent Zr, weight percent Ti and weight percent Fe lies within a polygon having as its corners the points defined by (a) 75% Zr-5% Ti-20% Fe (b) 60% Zr-5% Ti-35% Fe (c) 45% Zr-20% Ti-35% Fe (d) 75% Zr-20% Ti-5% Fe
