Shape Memory Alloys (SMAs) exhibit a complex material behaviour due to thermo-mechanical coupling. At present, the understanding of their under different loading conditions relevant civil engineering applications is lacking even though they have been widely used in past decade or so, for example mechanical at constant stress but variable temperature has not received much attention engineering. ...

When NiTi powder compacts containing Nb wires are heated above 1 170 8C, each Nb wire reacts with adjacent NiTi powders to form a eutectic liquid which wicks into the space between the remaining NiTi powders. This creates a macropore at the location of the Nb wire while eliminating the microporosity between NiTi powders which is filled with a NiTi/Nb eutectic phase after solidification. This no...

in this paper the response of cantilevered reinforced concrete (rc) beams with smart rebars under static lateral loading has been numerically studied, using finite element method. the material used in this study is superelasticshape memory alloys (se smas) which contains nickel and titanium elements. the se sma is a unique alloy that has the ability to undergo large deformations and return to t...

Nickel titanium (NiTi) shape memory alloy is a unique material displaying the shape memory effect and superelastic property making it attractive to the orthopedic field. However, with its high nickel content of∼50%, there is concern on health and safety when this material is implanted inside the human body for a prolonged period of time as toxic nickel ions may leach into the body due to corros...

Abstract Novel Nickel–Titanium (NiTi)-based shape memory alloy (SMA) pipe couplers were designed and developed. They are suitable for room-temperature ultrahigh vacuum (UHV) systems provide a quick compact solution at reasonable cost. Their use is particularly interesting restricted-access areas of particle accelerators as their installation/dismounting can be performed remotely by temperature ...
