Abstract Scope |
Material flow during SolidStir® extrusion process using the marker insert technique was analyzed in this study. SolidStir® extrusion is a solid-state thermomechanical material consolidation, mixing and extrusion. SolidStir extrusion process employs frictional heating and high pressure to induce plastic deformation in materials. The eco-friendly SolidStir® finds several engineering applications. However, little is known about the underlying mechanical of consolidation, mixing and material flow during the process. Gathering material flow data using markers will aid process understanding. In this study, AA 6061 feedstock rods with AA 7075 markers were used for SolidStir extrusion. After extrusion, the extrudate was sectioned and marker material was traced under a microscope using differential etching characteristic of the marker material. The flow data captured are reconstructed into 3D model to visualize the material flow during the SolidStir® extrusion process. A detailed characterization of the flow visualization will be presented and discussed. |
