Abstract: "The martensitic and the reverse transformation temperatures are directly related to the bending rigidity of the TiNi shape memory alloy (SMA) wire. The present paper aimed to obtain the functionally graded wire in which bending rigidity varies along the wire axis, and a new fabrication process of combined powder metallurgy and plastic working was proposed. A multi-layered TiNi compact with various Ti/Ni compositions was obtained by pulse current pressure sintering (SPS) which was hot-extruded into a wire. The resulting wires were investigated on the transformation temperatures and deformation properties. The differential scanning calorimetry measurements showed that functionally graded properties of transformation temperatures retained in the wire. The wire had both shape memory effect and superelasticity."
