Effect of thermomechanical training temperature on the two-way shape memory effect of TiNi and TiNiCu shape memory alloys springs

Materials Letters, 2003
Abstract In this article, the effect of thermomechanical training temperature on the two-way shape memory effect (TWSME) of TiNiCu and TiNi alloys springs were investigated. The results showed that when the springs were thermomechanical-trained at pure martensite, there is an increase of the recovery rate to a saturated value, the maximum recovery ...

Two-way Antagonistic Shape Actuation Based on the One-way Shape Memory Effect

Journal of Intelligent Material Systems and Structures, 2008
The stress created by the austenite transformation of mechanically constrained NiTi shape memory alloys (SMAs) significantly exceeds that required to deform (detwin) its low temperature martensitic phase. The one-way shape memory effect can therefore be used to create antagonistic, fully reversible flexural shape morphing structures by assembling ...

Influence of the microstructure on the stability of the intrinsic two-way shape memory effect

Materials Science and Engineering: A, 1999
Abstract This work presents a study of the development of the two-way shape memory effect (TWSME) and its degradation due to working cycles. An intrinsic TWSME was induced in wire specimens of two near equiatomic NiTi alloys by thermomechanical training.

Two-way shape memory effect and thermal cycling stability in Co35Ni35Al30 single crystals by low-temperature martensite ageing

Scripta Materialia, 2018
Low-temperature stress-induced martensite ageing at 400 K under a compressive stress of −500 MPa was applied along the [110] B2 ||[100] L10 -direction for improving the functional properties of ferromagnetic Co 35 Ni 35 Al 30 single crystals, which ...

Forming and two-way shape memory effect of NiTi alloy induced by laser shock imprinting

, 2019
Nickel–Titanium shape memory alloy (NiTi SMA) is an intelligent material that is a widely applied and studied. The two-way shape memory effect (TWSME) of the NiTi SMA has garnered particular attraction in the further miniaturisation and integration of ...
