Alloy

Scientists in Russia experimenting with advanced aluminum alloys have developed a new heat-resistant form of the material that can endure far higher temperatures, potentially serving as a cheaper and lighter alternative to heavy and expensive copper.

Both cars and electronic appliances require heat removal systems, typically made of steel or aluminum. That may soon change, though, as scientists have created two magnesium alloys which they claim can reduce the weight of such systems by a third.

Scientists in Japan working to stretch the limits of super-elastic materials have made a significant breakthrough, demonstrating a new iron-based alloy that can be deformed and regain its original shape even in extreme temperatures.

Radiation is famously damaging to materials, but now engineers at MIT have been surprised to discover that radiation may actually help certain alloys to self-heal, extending their useful lifetime. This could help inform future power plant designs.

Imagine if there were a metallic device that could be transported all squished down, but that would automatically "bloom" out into its useful form when heated. Well, that may soon be possible, thanks to a newly developed liquid metal lattice.

The 3D-printing of titanium-alloy objects does open up some intriguing possibilities. That said, the finished items aren't always as strong as they could be. New research suggests that adding copper to those alloys could make a big difference.

​Yesterday the North American Handmade Bicycle Show (NAHBS) wrapped up for another year, held once again in Sacramento, California. Among the many fascinating bikes that we checked out was a model that's built from Allite's revolutionary new Super Magnesium.

AA7075 is an aluminum alloy that's almost as strong as steel, yet it weighs just one third as much. Unfortunately its use has been limited, due to the fact that pieces of it couldn't be securely welded together. That's recently changed, however, thanks to the use of titanium carbide nanoparticles.

The creators of a new high-strength, low-weight metal alloy hope it will find a place as a midpoint between carbon fiber and lightweight aluminum in bicycle manufacture. Allite Super Magnesium​ is lighter and stiffer than aluminum, but not as expensive as carbon fiber.

Sandia engineers have developed the most durable metal alloy ever created. Made up of a combination of platinum and gold, the new material is 100 times more wear-resistant than high-strength steel, and the first metal alloy to join the same class as diamond. It also produces its own lubricant.
