Latest Patents

One of Grummon's latest patents is focused on the manufacture of shape-memory alloy cellular materials and structures by transient-liquid reactive joining. This invention discloses a method that utilizes pure niobium as a transient liquid reactive braze material. It allows for the fabrication of cellular or honeycomb structures, wire space-frames, and other sparse built-up structures using Nitinol, a near-equiatomic titanium-nickel alloy. The technique enables the joining of Nitinol shape memory alloys, which can be acquired in forms such as corrugated sheets, discrete tubes, or wires. When pure niobium is brought into contact with Nitinol at elevated temperatures, it liquefies below the melting point and flows into capillary spaces between the elements, forming a strong joint.
