Latest Patents
Roessler's latest patents include a "Lightweight high stiffness member and manufacturing method thereof." This invention focuses on creating a high-performance hybrid member suitable for applications requiring high stiffness, high temperature capacity, and lightweight characteristics. The hybrid member is constructed with a titanium alloy outer portion and a gamma titanium aluminide alloy inner portion, which are metallurgically bonded. This design allows for a modulus of elasticity greater than that of the titanium alloy outer portion, while maintaining a density equivalent to it. Additionally, the wear-resistant capabilities of the member can be enhanced through surface modification treatments or by affixing hardened fittings at the ends.
Another significant patent involves "Titanium aluminide alloys," which presents a family of gamma titanium aluminide alloys based on the intermetallic compound TiAl. These alloys are designed to exhibit mechanical properties and environmental capabilities suitable for high-temperature applications, such as those found in gas turbine and automotive engines. The preferred alloys contain a nominal aluminum content of about 46 atomic percent, along with niobium and tungsten to improve oxidation resistance.
