Fabrication of shape memory TiNi foils via Ti/Ni ultrafine laminates

Thin foils of TiNi shape memory alloy were produced by a diffusion treatment of ultrafine laminates with 50 μm thick composed of pure Ti and Ni layers. The M s and transformation heat of the TiNi foil were similar to those of the bulk alloys. The foil exhibited the shape memory effect with the recov...

More Information
Summary:Thin foils of TiNi shape memory alloy were produced by a diffusion treatment of ultrafine laminates with 50 μm thick composed of pure Ti and Ni layers. The M s and transformation heat of the TiNi foil were similar to those of the bulk alloys. The foil exhibited the shape memory effect with the recovery strain of about 8.6×10 −3.
