What is a shape memory alloy? Shape memory alloys or SMA's are metals that exhibit shape memory properties. The shape memory effect was first discovered in 1932 in a silver-cadmium alloy. It allows ...

The magnetic shape memory effect can be used for designing actuators where the element elongates based on the presence of a magnetic field. The elongation can be reversed fully either by the ...

The use of shape memory alloys to manufacture implantable medical devices represents a high-growth portion of the medical materials market today. The ability of these specialized alloys to expand or ...

Researchers used an Artificial Intelligence Materials Selection framework (AIMS) to discover a new shape memory alloy. The shape memory alloy showed the highest efficiency during operation achieved ...

Shape memory alloys (SMAs) possess the functional properties of shape memory and superelastic effects. They are therefore used in many engineering and biomedical applications. In the field of medicine ...

Shape-memory alloys, as their name implies, possess the ability to return to their original shape after being stretched or squished. Nickel-titanium shape-memory alloys, for example, are used as ...

Scientists captured live action details of the phase transitions of shape memory alloys, giving them a better idea how to improve their properties for applications. Known to many as muscle wire or ...

In order to address the challenges in fabrication NiTiNb ternary alloy structures, researchers from Shandong University (SDU) have proposed an alloy design strategy to prepare NiTiNb shape memory ...

Shape memory materials, also known as "metal muscles" or "artificial muscles," have the ability to snap back into their original shape after being stretched, squashed, bent, or otherwise deformed. If ...

A titanium-based shape-memory alloy is constructed without nickel to increase manufacturability and eliminate some biocompatibility concerns. With material properties that fall between standard ...
