AbstractThe present invention relates generally to a shape memory and/or super-elastic material, such as a nickel titanium alloy. Additionally or alternatively, the present invention relates to a super-elastic or pseudo-elastic material that has an initial transition temperature Af above a body temperature. The shape memory material can have a super-elasticity or pseudo-elasticity property at a temperature below the initial transition temperature Af of the material. For example, the shape memory material can have its workable temperature for producing super-elasticity or pseudo-elasticity of about 0 DEG C to 15 DEG C below the initial transition temperature Af. The shape memory material can be malleable at a room temperature, and become super-elastic or pseudo-elastic at a body temperature. In addition, the present invention relates to a method of making a shape memory or a super-elastic material. The treatment protocols can include but not limited to thermo-mechanical, thermo-mechanical, radiation, and ternary alloying treatments.
