SolidStir® is an in-situ thermomechanical material processing technology developed based on the principles of Friction Stir Welding and Processing (FSW/P). This process leverages severe plastic deformation and material flow at elevated temperatures under hydrostatic stress near the stirring tool. It enables shear mixing, microstructural refinement, consolidation, extrusion, and deposition—making it a versatile method for producing high-performance, defect-free components at scale. In this presentation, we demonstrate the conversion of chill-cast aluminum alloy 5083 into wrought deposits with enhanced tensile and high strain-rate properties. Cast 5083 plates were sectioned into smaller pieces to fit through the feed port and subsequently processed in the chamber to deposit refined wrought material. We conducted single-, double-, and multi-track depositions to analyze microstructure, mechanical properties, and bonding between layers and adjacent tracks. The results revealed significant improvements in strength, ductility, and strain-hardening ability. The results are discusses to demonstrate with a concept of infinite recycling. |
