Material, in the form of bars, tubes, profiles, wires, sheets, or bands, which is, at least partially, composed of a constituent showing a one-way shape memory effect, and a further inactive constituent hindering the one-way effect of the first, and which collectively exhibits a significant two-way
Material, in the form of bars, tubes, profiles, wires, sheets, or bands, which is, at least partially, composed of a constituent showing a one-way shape memory effect, and a further inactive constituent hindering the one-way effect of the first, and which collectively exhibits a significant two-way effect. The one-way shape memory constituent can be a Cu-Al-Ni, Cu-Al, TiV, Ti-Nb, Ni-Ti, or Ni-Ti-Cu alloy. Production of bi- or multi-constituent components by brazing, welding, roll bonding, extruding, powder metallurgical methods, hot isostatic pressing, or gluing, or by the application of metallic coatings (2) onto a core material (1) and subsequent diffusion treatment to produce an inactive surface layer (3).

An article exhibiting a two-way shape memory effect, which is comprised of a one-way shape memory constituent having at least two regions, wherein said constituent is caused to exhibit a two-way shape memory effect by the presence of a second constituent which induces stresses resisting said one-way
An article exhibiting a two-way shape memory effect, which is comprised of a one-way shape memory constituent having at least two regions, wherein said constituent is caused to exhibit a two-way shape memory effect by the presence of a second constituent which induces stresses resisting said one-way memory effect in at least one of said two regions, said second constituent being caused to be present in said article by at least one of brazing, welding, roll bonding, extrusion or hot isostatic pressing.
