Effect of Nd addition on the microstructure, mechanical properties, shape memory effect and corrosion behaviour of Cu–Al–Ni high-temperature shape memory alloys

Journal of Alloys and Compounds, 2020
The effects of rare earth element Nd on the microstructure, mechanical, shape memory properties and corrosion behaviour of Cu-13.0Al-4.0Ni-xNd (wt.%) high-temperature shape memory alloys were investigated in this paper. It was observed that the grains in

Shape Memory Effect in Quaternary NiTiHfPd Shape Memory Alloys beyond 200 °C

Journal of Materials Engineering and Performance, 2022
© 2022, ASM International.In this study, the effects of minor palladium (3 and 5 at.%) addition to ternary NiTiHf shape memory alloy (SMA) were investigated to design a high-temperature NiTiHfPd SMA. While most of the reported NiTiHfPd SMAs contain (Ni+Pd)-rich compositions, the (Ti+Hf)-rich compositions have not been studied to the same extent.

The effect of energy input on reaction, phase transition and shape memory effect of NiTi alloy by selective laser melting

, 2020
Selective laser melting (SLM) is used to fabricate near-equiatomic NiTi alloy from Ni–Ti mixed element powders. The influence of energy input on formability, microstructure, phase transition and shape memory effect of the NiTi alloy (atomic ratio is 1:1)

Elasticity and Shape Memory Effect of Shape Memory Fabrics

Textile Research Journal, 2008
An attempt has been made in this paper to investigate the distinction between shape memory effect and the wrinkle recovery property of cotton fabrics in terms of temperature sensitivity and elasticity. Elasticity is an inherent characteristic of typical wrinkle-free fabrics, because they are suppose to recover after the release of an external force ...

Phase field simulation on the grain size dependent super-elasticity and shape memory effect of nanocrystalline NiTi shape memory alloys

, 2020
Based on the Ginzburg-Landau's theory, the free energy function of polycrystalline system was modified by introducing an extra grain boundary energy, and a new two-dimensional phase field model considering the continuous variation of temperature was ...

Selective laser melting of NiTi alloy with superior tensile property and shape memory effect

Journal of Materials Science & Technology, 2019
It is a challenge to develop complex-shaped NiTi shape memory alloy parts by traditional processing methods, due to the poor machinability of NiTi alloy.

Modeling the shape memory effect of shape memory polymer

SPIE Proceedings, 2009
Dynamic mechanical analysis (DMA) tests are conducted on the styrene-based shape memory polymer (SMP) to investigate its state transition behaviors. Tensile tests at various constant temperatures are carried out to reveal the stressstrain- temperature relationship of the styrene-based SMP.

Triple Shape Memory Effect of Star-Shaped Polyurethane

ACS Applied Materials & Interfaces, 2014
In this study, we synthesized one type of star-shaped polyurethane (SPU) with star-shaped poly(ε-caprolactone) (SPCL) containing different arm numbers as soft segment and 4,4'-diphenyl methane diisocyanate (MDI) as well as chain extender 1,4-butylene glycol (BDO) as hard segment.

Multireusable Thermoset with Anomalous Flame-Triggered Shape Memory Effect.

ACS Applied Materials and Interfaces, 2019
While thermosets with high mechanical properties and shape memory capabilities have been developed in recent years, two main bottlenecks persist in their intrinsic nonreusability and flammability, especially for those shape memory thermosets used in ...
