New welding process  for formerly unweldable lightweight alloy AA7075
February 13th, 2019

Developed in the 1940s, AA7075 is an aluminum alloy that's almost as strong as steel, yet it weighs just one third as much. But its pieces  couldn't be securely welded together.

Led by Prof. Xiaochun Li, a team at the UCLA Samueli School of Engineering wanted to develop welding solution for that problem. They fabricated thin rods made of 7075 infused with minuscule particles of titanium carbide. These rods were then placed between the pieces of the aluminum alloy which were about to be joined, acting as a filler. When the rods and adjacent material were subsequently melted in an arc welding process, the nanoparticles eliminated an  uneven flow issue and good welds were obtained. Nanoparticles make the elements in the liquid metal solidify together more uniformly, thus preventing phase segregation, which was happening earlier.

The resulting welded joints have a tensile strength of up to 392 megapascals – by contrast, the commonly-used 6061 aluminum alloy has a weld strength of 186 megapascals. It is believed that post-welding heat treatments could boost the strength of the 7075 welds up to 551 megapascals, which is on par with the weld strength of steel.

The alloy is already used in items such as airplane wings and fuselages but sheets of it typically have to be riveted together.

ASU, Army Research Lab create new alloy with superhero-like strength

October 8, 2018
Now researchers from Arizona State University and the Army Research Laboratory have teamed and designed an alloy of copper and tantalum that can withstand extreme impact and temperature — bringing society one step closer to having real-life materials with superhero strength. Kiran Solanki, an associate professor in the Ira A. Fulton Schools of Engineering, is working on the copper and tantalum alloy, which has the potential to be used in protective equipment for the armed forces and on spacecraft for deep-space exploration.

A new Copper Graphene (G/Cu) nanocomposite alloy has been developed recently: the addition of 3% graphene to pure copper has proven to be an alloy that significantly improves the yield strength, tensile strength, and elastic modulus if compared to pure copper. Even though the electric conductivity decreases, the resulting material is still considered highly conductive.
