Shape memory polymer composite structures with two-way shape memory effects

Materials Letters, 2012
Abstract Shape memory polymers (SMPs) usually exhibit one-way shape memory effect. A simple and effective way to obtain two-way shape memory effect by SMP composite structures is proposed. The system consists of a SMP film with higher glass transition temperature Tg surrounded on another SMP cylindrical core with lower Tg.

Two-way shape memory effect of a TiNiHf high temperature shape memory alloy

Journal of Alloys and Compounds, 2004
The two-way shape memory effect in a Ti36Ni49Hf15 high temperature shape memory alloy (SMA) has been systematically studied by bending tests. In the TiNiHf alloy, the martensite deformation is an effective method to get two-way shape memory effect even with a small deformation strain.

Origin of two way shape memory effect in Cu-based shape memory alloys

Journal de Physique IV (Proceedings), 2003
Two-way shape memory effect (TWSME) should be trained by thermomechanical cycling or constrained aging. After constrained aging, oriented stress fields around precipitates and stabilized stress-induced martensite were found in Cu-Zn-Al alloys. The effect of these phases on TWSME has been studied by in-situ observations in TEM.

A three-dimensional phenomenological model for shape memory alloys including two-way shape memory effect and plasticity

Mechanics of Materials, 2019
The one-way and two-way shape memory effects (SMEs) as well as the thermal hysteresis represent fundamental properties when dealing with the design of detachable and thermally-stable connection systems based on shape memory alloys (SMAs). Such properties
