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 ...

Shape memory alloys (SMAs) provide new insights in biomedical engineering with the unique properties they exhibit, in applications such as cardiovascular stents, guide wires and organ frame retractors ...

Shape memory alloys are exotic materials that can be deformed at room temperature and return to their "remembered," ...

The secret to how steel hardens and shape-memory alloys snap into place lies in rapid, atomic-scale shifts that scientists have struggled to observe in materials. Now, Cornell researchers are ...

Alloys that can return to their original structure after being deformed have a so-called shape memory. This phenomenon and the resulting forces are used in many mechanical actuating systems, for ...

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 team from Lanzhou University of Technology have developed a novel NiTi shape memory allow (SMA) with harmonic ...

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 ...

Besides superfluous features like touchscreens and internal cameras, basic refrigerator technology hasn't changed much in decades. They still chill your milk by way of chemical refrigerants and ...
