Abstract Scope |
Shear assisted processing and extrusion (ShAPE) is a newly developed solid-state processing technique and emerging as a potential processing method of microstructural modification to improve the performance of alloys. In this study, the ShAPE process has been utilized to extrude Al alloys to achieve better strength and ductility with refined microstructure. Commercial Al7075 alloy extruded in the form of rods with 5 mm diameter. Microstructure of ShAPE extruded materials showed very significant grain refinement and homogenously distributed precipitates throughout the extruded rod. Quantitative microstructural characterization was performed using scanning electron microscopy (SEM), back-scatter electron microscopy (EBSD) and transmission electron microscopy (TEM). Mechanical response was evaluated by performing tensile test of the extruded rods. |
