A new research paper maps how laser additive manufacturing is bringing shape memory alloys closer to practical 4D printing.

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 ...

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 ...

Shape memory alloys (SMA) remember their original shape and return to it after being heated. Similar to how a liquid transforms into a gas when boiled, SMAs undergo a phase transformation when heated ...

Shape memory alloys (SMAs) are metallic materials capable of undergoing reversible, diffusionless phase changes that enable two hallmark behaviours: the shape memory effect and superelasticity. In the ...

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 ...

Iron-based shape memory alloys (Fe-SMAs) are emerging as multifunctional materials for the repair, strengthening and life-extension of civil infrastructure. Exploiting the shape memory effect and ...

Researchers in China have discovered a combination of metals that could have great potential for the next generation of memory-storage devices, which will use "phase-change" memory instead of Flash ...

A University at Buffalo-led team of researchers has developed a method for producing advanced nanoparticles that could ...

This atomistic model showing the coexistence of two solid phases of NiTi: austenite (blue), stable at higher temperatures, and martensite (brown), stable at lower temperatures. The martensite region ...
