Two-way Antagonistic Shape Actuation Based on the One-way Shape Memory Effect
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 opposing pairs of linear contractile SMA actuato...
متن کاملTwo-way shape memory effect of a TiNiHf high temperature shape memory alloy
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. When the TiNiHf alloy is deformed at a full martensite state, the deformation mechanism is the martensite orien...
متن کاملA Shape Memory Polymer with Improved Shape Recovery
Thermally actuated shape memory polymers (SMPs) interest, both academically and industrially, due to their ability to memorize a permanent shape that is set during processing and a temporary shape that is later programmed by manipulation above a critical temperature, either Tg or Tm. However, the thermal triggering process for SMPs is usually retarded compared to that of shape memory alloys, be...
متن کاملCombined One-Way and Two-Way Shape Memory in a Glass-Forming Nematic Network
Past research in the field of shape memory polymers has led to significant advancements in the areas of so-called one-way and two-way (reversible) shape memory. While one-way shape memory polymers allow indefinite fixing of a temporary shape until triggered thermally to recover to an equilibrium shape, twoway shape memory polymers feature muscle-like contraction on heating and expansion on cool...
متن کاملStudy of Dislocations Generated by Thermal Cycling in Ni-Ti-Co Shape Memory Alloys
In the present work we report some results concerning the evolutions of transformation temperatures and microstructure during thermal cycling in Ti47%Ni 3% Co (atomic percent). In the case of hulk material (obtained by a conventional solidification method) high amounts of dislocations l'onn during cycling, which produce a considerable evolution of the transformation temperatures (up LO -40K). w...
