Strain glass-induced switch from transformation plasticity to reversible superelasticity in Ti-Zr-Ni-Cu alloys

Materials Research Letters, 2023
Reversibility of phase transformation, a basic requirement for functional properties of shape memory alloys, such as superelasticity, is severely affected by plastic deformation.

Effect of torsion deformation and electric pulse treatment on transformation behaviour and superelasticity of Ti-50.8 at.% Ni wire

Materials & Design, 2022
The functional stability of Ti-50.8 at.% Ni wires (diameter: 0.5 mm) was improved by torsion deformation coupled with electric pulse treatment. The effects of torsion deformation (T = 5–50 turns) and electric pulse treatment (f = 50–400 Hz and t = 50 ...

Surface effects on the superelasticity of nanohelices [PDF]

Journal of Physics: Condensed Matter, 2012
Helical nanomaterials with superelasticity have a wide range of promising applications in micro-/nanoelectromechanical systems. Based on the theory of surface elasticity, we present a nonlinear rod model to investigate the superelasticity of nanohelices. Our results demonstrate that the superelasticity of nanohelices exhibits a distinct size dependence
