Shape memory polymers based on reversible supramolecular interactions have invoked growing research interest, but still suffer from limitations such as poor mechanical strength and finite shape memory performance. Here, we present a novel mechanical stretchable supramolecular hydrogel with a triple shape memory effect at the macro/micro scale. The introduction of a double network concept into s...

The three-point-bending shape memory properties, microstructure, and magnetic properties of Fe40.95Ni28Co17Al11.5Ta2.5B0.05 (at.%) alloys were investigated. results showed a martensitic transformation in the samples that aged at 700 °C for 6 12 h under applied fields 0.05 7 Tesla. start temperature increased from −113 to −97 as aging times h. Increasing Tesla, temperatures higher temperature. B...

The properties and cost have made the Nickel-Titanium (NiTi) shape memory alloys (SMA) attractive for a variety of applications wherein shape memory effect (SME) / superelasticity (SE) and biocompatibility are important. Anisotropy of the shape recovery associated with shape memory effect strongly depends on the type of r 30 minutes in air) Ti-Rich Ni-Ti SMA (Ni51at%Ti) when subjected to cold r...

In many applications, Cu base Shape Memory Alloys (SMA S) are a more economical alternative to other systems showing Shape Memory Effect (SME). However, bearing in mind the potential use of these SMA it is becoming increasingly important to develop suitable techniques to join them satisfactorily to themselves and to another material. In that sense, a liquid phase diffusion bonding process with ...
