  2. Depleted uranium - Wikipedia

    en.wikipedia.org/wiki/Depleted_uranium

    Natural uranium contains about 0.72% 235 U. Depleted uranium has lower mass fractions—up to three times less—of 235 U and 234 U than natural uranium. Since 238 U has a much longer half-life than the lighter isotopes, DU is about 40% less radioactive than natural uranium.

  4. Stakalloy - Wikipedia

    en.wikipedia.org/wiki/Stakalloy

    Stakalloy has improved metallurgical properties over other depleted uranium alloys, such as staballoy, being more viable as a structural alloy where a combination between high strength and high density is required. [1] Changes include that of density, hardness, ballistic properties, and machinability. [1]

  6. Ducrete - Wikipedia

    en.wikipedia.org/wiki/Ducrete

    DUCRETE (Depleted Uranium Concrete) is a high density concrete alternative investigated for use in construction of casks for storage of radioactive waste. It is a composite material containing depleted uranium dioxide aggregate instead of conventional gravel, with a Portland cement binder.

  7. Rockwell scale - Wikipedia

    en.wikipedia.org/wiki/Rockwell_scale

    A Rockwell hardness tester. The Rockwell scale is a hardness scale based on indentation hardness of a material. The Rockwell test measures the depth of penetration of an indenter under a large load (major load) compared to the penetration made by a preload (minor load). [1]

    This is when uranium glass reached the height of its popularity in the United States between 1958 and 1978, with more than 4 million pieces of decorative uranium produced, according to Oak Ridge ...

  9. Ferrouranium - Wikipedia

    en.wikipedia.org/wiki/Ferrouranium

    In ferrous alloys, uranium increases the elastic limit and the tensile strength. In high speed steels , it has been used to increase toughness and strength in amounts between 0.05 and 5%. [ 5 ] Uranium-alloyed steels can be used at very low temperatures; nickel-uranium alloys are resistant to even very aggressive chemicals, including aqua regia .
