  • Patent number: 10316379
    Abstract: Steel compositions are provided. A steel composition may include iron; from 0.015 to 0.06 wt. % carbon; from 9 to 12 wt. % chromium; from 0.75 to 1.5 wt. % manganese; from 0.08 to 0.18 wt. % molybdenum; from 0.10 to 0.30 wt. % silicon; from 0.2 to 1.0 wt. % vanadium; from 0.05 to 1.2 wt. % niobium; and optionally, an amount of an additional precipitate forming alloying element. Methods of making the steel compositions are also provided.
    Type: Grant

  • Publication number: 20150167128
    Abstract: In one aspect of the invention, an alloy includes a first element comprising magnesium (Mg), titanium (Ti), zirconium (Zr), chromium (Cr), or nickelaluminum (NiAl), a second element comprising lithium (Li), calcium (Ca), manganese (Mn), aluminum (Al), or a combination thereof, and a third element comprising zinc (Zn). According to the invention, nanoscale precipitates is produced in the magnesium alloy by additions of zinc and specific heat-treatment. These precipitates lower the energy for dislocation movements and increase the number of available slip systems in the magnesium alloy at room temperature and hence improve ductility and formability of the magnesium alloy.

  • Patent number: 7874060
    Abstract: An optics element, such as an optical, IR, or X-ray mirror or mirror segment, is made by a combination of replication and lamination by depositing a first metallic layer on a replicating surface of a master or mandrel, depositing a light weight backing layer that adheres on the first metallic layer, and depositing a cover layer that adheres on the backing layer whereby the optics element comprises an in-situ deposited composite lamination of the first metallic layer, the backing layer, and the cover layer.
