Shape memory alloys are exotic materials that can be deformed at room temperature and return to their "remembered," pre-deformed shape when heated. They are used in a broad range of applications, such ...

This Collection welcomes original research on shape memory alloys, with a focus on their synthesis, structural and functional characterisation, and emerging applications. Shape memory alloys (SMAs) ...

Endowed with the power of memory, certain alloys can magically return to their original shape when heated or deformed. However, the repeated back-and-forth between the original and new configuration ...

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 ...

Researcher Ken Gall uses this thermomechanical test frame to determine the maximum possible shape change of his team's shape-memory polymer. Shape-memory alloys and polymers are the contortionists of ...

Researchers have significantly improved a new joining technology, interlocking metasurfaces (ILMs), designed to increase the strength and stability of a structure in comparison to traditional ...

General Motors has been awarded $2.7 million by the Department of Energy to create a working prototype engine using Shape Memory Alloys (SMA). The idea is for the prototype to use SMA tech to capture ...

Can the Thermal Properties of Shape Memory Alloys be adjusted for Heating and Cooling Applications? Thermal parameters, especially thermal expansion, play a key role in the performance of shape memory ...

In a study published in Materials & Designs, researchers from Texas A&M University and Sandia National Laboratories have made significant advancements in a new joining technology called interlocking ...

Robonaut 2 represents a sequel to a NASA/DARPA project from 10 years ago, and was begun three years ago. In both cases, the idea was to create humanoid robots that will work alongside humans on earth ...

How a special nitinol compound and 3D printing was used to create the shape-shifting antenna. An overview of materials and heating problems they encountered, and how they overcame them. The test ...
