| Abstract Scope |
Friction Extrusion (FE) is a newly developed solid phase processing technique and emerging as a potential processing method for microstructural modifications with desired properties. In this study, the FE process has been utilized to extrude both AA6061 and AA7075 alloy to achieve better strength and ductility with refined microstructure. Texture and microstructure evolution during extrusion are investigated in detailed via scanning electron microscopy (SEM), electron backscatter diffraction (EBSD) and transmission electron microscopy (TEM) analysis. Refined microstructure, uniform distribution of second phase particles and shear type texture development was observed in FE extruded rod. The uniform distribution and refinement of the particles resulted in faster aging kinetics. Smoothed particle hydrodynamics (SPH) simulation method was utilized to understand the material flow, temperature evolution, strain and strain rate during extrusion process. |
