Method for seamless joining and repair of metal parts using ultrasonic additive manufacturing
TS-050479 — This invention provides a method for repairing metal parts by removing and replacing worn, damaged, or defective metal material. It also serves as a method for seamlessly joining metal sheets and other parts while retaining the original temper of the joined parts. This technology, based on ultrasonic additive manufacturing (UAM), achieves strong joints and repairs by enabling the filling of a channel that has been cut, formed, or otherwise created in a metal structure or between two metal structures.
The aircraft industry lacks a robust method for joining metal sheets, structures, and assemblies together in wings, fuselages, and engines. Fusion based welding methods cannot always be used because they create heat-affected zones, which reduce the mechanical performance of material around the wel…

Integrally Joined Stainless Steel-NiTi Medical Devices
TS-050057 — A method for manufacturing surgical tools and implants with strong, gapless joints between NiTi (Nitinol) and stainless steel to capitalize on the best properties of both materials.
NiTi (Nitinol) is widely accepted and used for medical devices such as surgical tools and implants due to its biocompatibility and unique thermal-mechanical properties which provide super-elastic or shape memory responses. However, there are currently no commercial solutions for joining of NiTi to…

Integration of smart materials into surgical tools and medical devices using vaporizing foil actuator technology.
TS-045092 — Shape memory alloys are metals that "remember" their original shape when deformed and can return to their initial shape when heated. These shape memory alloys cannot currently be welded to other alloys, which significantly limits their use. Current state-of-the-art methods of joining sha…

Novel Method for Welding of High-Strength Aluminum Alloys
TS-014735 — A cost-effective method that drastically increases high-strength aluminum alloys' resistance to environmental degradation.
Manufacturers seek low-density, high-strength metals that can withstand environmental stress. High-strength aluminum alloys (AAs) are increasingly used for light-weighting in automotive and aerospace structure applications, but welds with such alloys are susceptible to environmental degradation, w…
