Abstract Scope |
Solid Stir Extrusion (SSE), a novel and innovative process based on friction stir technology has been introduced with Al 6061 as a model material. The process is designed to obtain final solid-state extrudate of desired shape. As an alternate solid-state manufacturing technique, SSE process enjoys advantages such as lower power consumption, continuity over larger time frame, applicability over a wide range of materials, and possibility of rescaling to preferential design requirements. The process outcomes have been correlated with detailed microstructural and mechanical characterization. Extrudate exhibited refined equiaxed grain morphology with enhanced ductility as compared to the base material. Post process aging further enhanced the mechanical performance of the extrudate. Additionally, an attempt was made to correlate independent process variables and process-based outcomes in SSE through a conceptual model which has been validated through extensive experimental runs. The metal recycling capability of this process was demonstrated using compacted aluminum chips. |
