  • Titanium alloys
    Patent number: 12344918
    Abstract: A titanium alloy comprises, in weight percent based on total alloy weight: 3.5 to 4.5 aluminum; 1.0 to less than 3 tin; 1.0 to 3.0 zirconium; 2.0 to 5.5 molybdenum; 2.0 to 4.25 chromium; 0.01 to 0.03 silicon; titanium; and impurities; and wherein an aluminum equivalent value of the titanium alloy is 6.0 to 6.9.

  • Peening media and processes for producing and using peening media
    Patent number: 11376712
    Abstract: Processes for producing peening media, the peening media produced from such processes, and methods of using such media. Particles are provided having surfaces that are formed of or contain a metal that exhibits solubility for oxygen in a metallic phase so as to increase in surface hardness as a result of solid solution strengthening due to oxidizing of the surfaces of the particles. The particles are subjected to a thermal process in an oxygen-containing atmosphere at a process temperature and for a process duration sufficient to oxidize the surfaces of the particles to increase the surface hardness of the particles while not forming an oxide layer that encases the particles.
