| Abstract Scope |
Friction extrusion (FE) is an solid-phase processing technique that produces high-performance metal wires/rods from solid billets, powders, or scraps in a single step without melting. The process involves high strain, strain rate, and elevated temperature to drive solid-state diffusion and dynamics recrystallization, enabling superior product properties. Additionally, material flow during FE affects phase formation, material mixing, and microstructure homogenization. While material flow and thermomechanical conditions are commonly linked to process parameters, the impact of die geometry on these factors remains poorly understood. To address this, a smoothed particle hydrodynamics (SPH) model is developed to simulate FE with five distinct die geometries to reveal in-situ material flow and thermomechanical behavior. Experimental validation, supported by ex-situ EBSD characterization, demonstrates the model’s accuracy and highlights the role of die geometry in enhancing extrudate performance. This work facilitates FE’s application in novel alloy development, such as thermal conductive CNT-reinforced materials and metal waste upcycling. |
