A chance discovery in 1959 by military scientists led to Nitinol, a metal that remembers its shape. This nickel-titanium ...

Laser powder bed fusion, a 3D-printing technique, offers potential in the manufacturing industry, particularly when fabricating nickel-titanium shape memory alloys with complex geometries. Although ...

Researchers have found special atomic patterns called quasicrystals in 3D-printed aluminum alloys. Quasicrystals increase the strength of 3D-printed aluminum, the researchers discovered, making it ...

When is a crystal not a crystal? When it’s a quasi-crystal, a paradoxical form of metal recently found in some 3D printed metal alloys by [A.D. Iams et al] at the American National Institute for ...

Engineers have discovered a way to make an ultra-strong stretchy metal that could enable the creation of shape-shifting aircraft. The new metal is an alloy made up of titanium and nickel. It's as ...

Extrusion, which can produce complex parts made of lightweight metals, is an increasingly important manufacturing process for everything from buildings to electric vehicles. Pacific Northwest National ...

Engineers have spent decades trying to build metals that do not snap, melt, or grind away under extreme conditions, and for a long time the tradeoffs seemed unavoidable. Push strength too far and a ...
