  • Stakalloy: a uranium-vanadium-niobium alloy
    Patent number: 6726876
    Abstract: A ternary alloy of uranium, referred to as stakalloy, having improved machinability is formed of niobium, vanadium and uranium. The ternary alloy is formed with the percent by weight of vanadium being between the gamma eutectoid (1.0 percent by weight vanadium) and the eutectic (4.5 percent by weight vanadium) compositions, and the niobium content being between 0.01 to 0.95 percent by weight and the balance being uranium. Stakalloy has different density, improved metallurgical properties, such as different hardness, machinability, and ballistic properties from other uranium alloys, making it useful as a structural alloy where high density and high strength are important.

  • Hypereutectoid and hypoeutectic binary uranium-vanadium alloys
    Patent number: 5963777
    Abstract: Binary alloys of uranium and vanadium having high hardness and strength prepared by selectively adjusting both the composition of the alloy and the solutionization temperature between the gamma-eutectoid and the eutectic points.
