| Abstract Scope |
This presentation covers progress toward development of Shear Assisted Processing and Extrusion (ShAPE) for recycling of secondary metal scrap directly into semi-finished parts. Unlike conventional extrusion where the billet is rammed against a die in strictly linear fashion, ShAPE utilizes a rotating die or billet to impart severe plastic deformation during pressing. Superposition of linear and rotational shear enables extreme grain refinement, intermetallic break-up, and homogenous dispersion of second phases leading to process, microstructure, and property advantages. The ability to extrude pre- and post-consumer scrap without adding primary metal can substantially reduce lifecycle energy consumption and carbon emissions compared to conventional recycling. ShAPE offers a promising new pathway for more sustainable metals production since mining and refining of primary metal can be eliminated. ShAPE process development for aluminum and friction extrusion of titanium will be highlighted with accompanying microstructural analysis and mechanical properties compared to conventionally extruded primary material. |
