Nanoparticle-enabled phase control for arc welding of unweldable aluminum alloy 7075
Abstract
In contrast to steels, fusion welding high strength aluminum alloys such as AA7075 is notoriously difficult. Here, the authors add nanoparticles to a weld filler rod to successfully weld AA7075 without hot cracks or loss of strength at the weld.
