Shape memory alloys (SMAs) are capable of regaining their original shape after deformation via heating. This effect relies on a reversible diffusionless transformation between the starting austenite ...

Abstract: The return of commercial supersonic flight requires innovative solutions to be developed that meet noise and efficiency requirements for overland flight. To study such a possibility NASA is ...

A collaborative effort by leading Japanese institutions has led to the development of copper-based alloy (Cu-Al-Mn) with a unique “shape memory effect” at a low temperature of -200°C (−328 °F). This ...

Researchers have developed a novel copper-based alloy that exhibits a special shape memory effect at temperatures as low as -200°C. The work has been published in the journal Communications ...

ANTIOCH, Calif. — Nanomuscle Inc. has tapped the properties of shape-memory alloys to yield small actuators that it believes could address a large applications niche between macroscopic motors and ...

In contrast to conventional electromagnetic coil-based motors and solenoids, the DM-01 actuator from MIGA Motor Co uses shape-memory alloy for its prime mover. Suitable for applications such as ...

NASA engineers have added a new twist to a cutting edge aerospace technology by demonstrating how a new Shape Memory Alloy (SMA) actuator can fold a 300-lb (136 kg) wing section from an F/A-18 Hornet ...

A study led by Tohoku University, Iwate University, The Japan Aerospace Exploration Agency (JAXA), National Astronomical Observation of Japan, Tokyo City University, and Kyoto University developed a ...
