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 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 ...

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 unique properties of shape-memory alloys such as nitinol have lent themselves to a variety of applications across numerous industries, including medical devices. These common shape-memory alloys, ...

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 ...

Even after the hundredth time the material returns to its original shape when heated. Using computer simulation, Alberto Ferrari calculated a design proposal for a shape memory alloy that retains its ...

When common metallic materials are subjected to an applied stress, deformation occurs. Small amounts of deformation are reversible, such that the material returns to its initial shape when the stress ...

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 ...

A German research team has prototyped an extraordinary heating/cooling system that stresses and unloads nickel-titanium "muscle wires" to create heated and cooled air at twice the efficiency of a heat ...
