Abstract
Functionally graded NiTi structures benefit from the combination of the smart properties of NiTi and those of functionally graded structures. This article provides experimental data for thermomechanical deformation behaviour of microstructurally graded, compositionally graded and geometrically graded NiTi alloy components, related to the research article entitled “Functionally graded shape memory alloys: design, fabrication and experimental evaluation” (Shariat et al., 2017)

The stress–strain diagrams of such shape memory components were obtained using tensile testing machine at various testing temperatures. Compositionally graded NiTi strips were created using sputtering deposition of a thin Ni layer and then diffusion annealing to encourage ingression of Ni through the thickness of the NiTi structure. After tensile deformation, the NiTi strips were subjected to heating and cooling cycles and the shape changes of the strip samples were recorded using a digital camera.

Here, Ti-50.5 at%Ni wires of 1.2 mm in diameter were used. The wires were initially solution treated at 1123 K for 1 h to eradicate any effect of prior treatments including cold working and ageing. The wires were then rolled at room temperature to 50% elongation in length. The microstructural gradient along the length of the wires was created using a tube furnace with temperature distribution profile shown in <xref rid="f0005" ref-type="fig">Fig. 1</xref>(b). The wires of 100 mm in length were heat treated for 1 h within a temperature field of 630–810 K along the whole gauge length as illustrated in <xref rid="f0005" ref-type="fig">Fig. 1</xref>(b). <xref rid="f0005" ref-type="fig">Fig. 1</xref>(c) shows the tensile deformation behaviour of the wire segments of 70 mm in length taken from the low temperature end of the heat treated wires, i.e. the annealing temperature range was 630–783 K. The tensile tests were carried out using an Instron testing machine at several testing temperatures. The deformation was conducted in water for elevated temperatures using a liquid bath. The strain rate was ~3×10<sup>−4</sup>/s. This strain rate was low enough to ignore the thermal effect associated with the latent heat of the martensitic phase transformation. A fresh sample was used for each test to avoid the effect of deformation cycles. As see in <xref rid="f0005" ref-type="fig">Fig. 1</xref>(c), the deformation at 303 K showed a clear presence of R-phase transformation at the early stage of deformation. The level of stress–strain curve over stress-induced transformation increased and the recovery of transformation strain improved as the testing temperature increased. Samples deformed at 323 K and 333 K exhibited good pseudoelasticity. At 333 K, the stress windows of 210 MPa and 320 MPa over forward and reverse transformations, respectively, were achieved.</p></sec><sec id="s0030"><label>2.2</label><title>Graded aging</title><p>Ageing is applied mostly to nickel-rich alloys of >50.5 at%Ni for improving the pseudoelasticity. Ageing is affected by several parameters including alloy composition, ageing temperature and ageing time, as well as the solution treatment conditions of the alloys. Here, Ti-50.8 at%Ni wires of 0.8 mm in diameter were used. The wires were initially solution treated at 1123 K for 1 h in argon to eliminate the effects of all prior treatments. <xref rid="f0010" ref-type="fig">Fig. 2</xref>(a) shows the deformation behaviour of those wires after isothermal ageing at different temperatures ranging from 573 K to 773 K for 2 h. The aging temperature is shown on each curve. The samples were deformed in tension at 295 K. It is seen that by the increase of aging temperature, the stress plateau level decreased and the samples exhibited less pseudoelasticity.<fig id="f0010"><label>Fig. 2</label><caption><p>Deformation behaviour of Ti-50.8 at%Ni wires under tension; (a): isothermally aged samples at different aging temperature, (b): graded aged samples at different testing temperatures.</p></caption><alt-text id="at0010">Fig. 2</alt-text><graphic xlink:href="gr2"></graphic></fig></p><p>Graded ageing can be done by either temperature gradient or time gradient. Here, the tensile experimental data for Ti-50.8 at%Ni wires aged over temperature gradient is presented. The wires were aged within a temperature gradient of 573–773 K along their length.

It is known that martensitic transformation in NiTi is sensitive to alloy composition <xref rid="bib8" ref-type="bibr">[8]</xref>. The compositional gradient can be achieved through the thickness direction of 2D NiTi structures, such as NiTi thin plates and films <xref rid="bib9" ref-type="bibr">[9]</xref>.</p><p>In this experiment, a Ti-50.07 at%Ni sheet of 0.22 mm in thickness was used. Strips of 40 mm×5 mm were prepared from the NiTi sheet. The samples were annealed at 1123 K for 1 h in vacuum. Then, a Ni thin film of ~500 nm in thickness was deposited on the samples by means of DC magnetron sputtering under argon protection. The coated samples were then annealed at 1223 K in vacuum for 3 h to encourage diffusion of Ni into the NiTi plate. This provided a composition range of 50.07–50.8 at%Ni across the thickness direction of the strip specimens. Various levels of tensile deformation can be applied to the compositionally graded samples before the application of thermal cycles. Here, we present the experimental data for deformation behaviour of a sample during one complete thermal cycle after tensile deformation to 15%. The shape change of the strip during one cooling and heating cycle (a fishtail-like motion) was recorded by a digital camera and is presented as a video component, which accompanies the electronic version of this manuscript.

As observed, upon cooling from 315 K to 283 K, the strip progressively bended in the counter clockwise direction to a maximum curvature. Then, as the temperature was further decreased to 223 K, the strip bended back in the clockwise direction. This behaviour repeated upon heating. The strip first bended in the counter clockwise direction upon increase of temperature up to 298 K and reached to the maximum curvature. Then, it gradually curved back as heated to 345 K.
