There is disclosed a method for chemically bonding TiNi materials to Nitinol constructs, comprising placing a Nitinol construct within a mold and packing a powder combination comprising Ti powder and Ni powder, and powder comprised of zero or more of the elements Cu, Hf, Zr, Pt, Pd, Au, Cd, Ag, Nb, Ta, O, N, B, and H, into the mold. The method further includes initiating a process of self-propagating high temperature synthesis of the powder combination within the mold to create a chemical bond between the Nitinol construct and a resulting TiNi foam to thereby create a Nitinol and TiNi assembly. 1. A method for chemically bonding TiNi materials to Nitinol constructs , comprising:placing a Nitinol construct within a mold;packing a powder combination comprising Ti powder and Ni powder, and powder comprised of zero or more of the elements Cu, Hf, Zr, Pt, Pd, Au, Cd, Ag, Nb, Ta, O, N, B, and H, into the mold; andinitiating a process of self-propagating high temperature synthesis of the powder combination within the mold to create a chemical bond between the Nitinol construct and a resulting TiNi foam to thereby create a Nitinol and TiNi assembly.2. The method of further comprising removing the Nitinol and TiNi assembly from the mold.3. The method of wherein the resulting Nitinol and TiNi assembly comprises a Nitinol construct and the TiNi foam comprises one or more TiNi mating couplers.4. The method of wherein the TiNi mating couplers are used to attach the Nitinol and TiNi assembly to an external structure.5. The method of further comprising applying heat to the Nitinol and TiNi assembly to thereby transfer force to the external structure from the Nitinol and TiNi assembly.6. The method of wherein the atomic percentage of Ni powder in the powder combination is in the range of 45% to 56%.7. The method of further comprising placing the Nitinol construct within the mold and the powder combination within the mold into one of a vacuum and inert gas environment prior to ...
