In this video I talk about an amazing type of metal called a shape memory alloy. The specific one in this video is called nitinol. It is an alloy of nickel and titanium. It forms an amazing structure ...

A rover on the Moon has metal wheels that can flex around rocky obstacles, then reshape back to their original form. On Earth, surgeons install tiny mesh tubes that can dilate a heart patient’s blood ...

As air traffic is projected to increase dramatically over the next decade, reducing noise pollution becomes an even more necessary and demanding challenge. Decades of research have been dedicated to ...

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 ...

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 ...

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 ...

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 ...
