  • Zirconium-gallium alloy and structural components made thereof for use in nuclear reactors
    Patent number: 5122334
    Abstract: A zirconium-base alloy including gallium in amounts effective to improve creep strength of the alloy. The Zr-base alloy can include up to 1 wt. % Ga, up to 0.5 wt. % oxygen, up to 1 wt. % Sn and up to 1 wt. % total of Fe, Cr and V. For instance, the alloy can include 0.5-0.5 wt. % Ga, 0.1-0.7 wt. % Sn, 0.1-0.5 wt. % Fe, 0.15-0.4 wt. % V, 0-0.5 wt. % Cr, 0.1-0.25 wt. % oxygen, balance Zr and unavoidable impurities. The alloy is particularly useful as a component of a fuel assembly such as a fuel tube.
