June 18, 2019 – An advanced manufacturing process to produce nanostructured rods and tubes directly from high-performance aluminum alloy powder — in a single step — was recently demonstrated by researchers from the Pacific Northwest National Laboratory. Using a novel Solid Phase Processing approach, the research team eliminated several steps that are required during conventional extrusion processing of aluminum alloy powders, while also achieving a significant increase in product ductility (how far a material can stretch before it breaks). This is good news for sectors such as the automotive industry, where the high cost of manufacturing has historically limited the use of high-strength aluminum alloys made from powders.
The team’s research is described in the paper “High Ductility Aluminum Alloy Made from Powder by Friction Extrusion,” published in the June 2019 issue of Materialia.
