Latest Patents
Koczak's latest patents include an "Elevated temperature aluminum-titanium alloy by powder metallurgy process." This patent describes an aluminum-titanium alloy consisting essentially of aluminum, 4-6 wt. % titanium, 1-2 wt. % carbon, and 0.1-0.2 wt. % oxygen. The alloy is characterized by a fine, homogeneous dispersion of Al.sub.3 Ti particles, which enhances its strength, ductility, and creep resistance at temperatures exceeding 200 degrees Celsius. The process involves rapidly solidifying an aluminum-titanium melt and mechanically alloying it in the presence of a carbon-bearing agent.
Another significant patent is the "In situ process for producing a composite containing refractory material." This invention outlines a method for creating a composite with a refractory material dispersed in a solid matrix. The process involves introducing a gas into a molten composition and reacting it with a refractory carbide-forming component. The resulting liquid composite is cooled to form a solid material, which can include refractory borides or nitrides.
