Alloy

Scientists experimenting with the makeup of next-gen metals have developed a novel, copper-based alloy they say would be simple to produce at scale, and boasts unparalleled elasticity at room temperature.

Engineers have developed a new 3D-printed titanium alloy with a unique microstructure that makes it ultra-strong. Not only is it stronger than other forms of titanium, but it has the highest strength-to-weight ratio of any 3D-printed metal ever made.

With new manufacturing techniques comes the opportunity for new metal alloys with a range of possible properties. A team of researchers has now developed a new 3D-printable alloy with a specific nanostructure that makes it ultra strong and ductile.

Scientists experimenting with the makeup of metal alloys used for medical implants have made a significant breakthrough, resulting in a biomaterial with the flexibility and wear resistance needed for long-term stints in the human body.

Instead of being cast as a solid piece of material, 3D-printed items can include material exactly where it's needed. The Elix handlebar stem takes this approach to a performance-boosting – and pocketbook-emptying – extreme.

With a view to constructing more durable components that can withstand the very harsh environments in an around aircraft and jet engines, NASA researchers have developed a novel metal alloy with an impressive set of qualities at extreme temperatures.

City University of Hong Kong researchers have accidentally discovered a first-of-its-kind high-entropy alloy that retains its stiffness, and actually becomes springier, instead of softening at high temperature. No other known metals behave this way.

Researchers from the Chinese Academy of Sciences have found that Earth’s inner core may be stranger than we thought. Rather than a plain solid, new simulations suggest it exists as a superionic state of matter, partway between a liquid and a solid.

As useful as steel is, its main weakness may be its vulnerability to corrosion. Researchers in Korea have now developed a new alloy coating that boosts steel’s resistance to rust, by adding a simple extra step in the surface treatment.

If you wanted to 3D-print an object that was magnetic in some areas only, you'd have to print two items out of different metals, then join them. A new technique, however, allows for the printing of single objects with gradient magnetic qualities.

Scientists at Rice University have cooked up a new alloy with a unique and diverse set of attributes that could prove highly effective at protecting steel from corrosion, and can even heal itself when damaged.

A new, surprisingly simple method merges two metals into one nanocrystal structure. This could allow almost any two metals to be combined, creating brand new types of intermetallic nanocrystals that could be useful for a whole range of applications.
