Abstract Scope |
The present work deals with the Shear Assisted Processing and Extrusion (ShAPE) of AA2024 tubes and strength optimization using commonly applied tempers of T3510 and T8510. The ShAPE process enables extruding AA2024 at an extrusion speed of 7.4 m/min and 480⁰C die temperature, which is otherwise beyond the extrudability limit of this alloy using a conventional extrusion technique. The ultimate tensile strength at different tempers (466 MPa for T3510 and 503 MPa for T8510) exceeds the ASTM/ASM (minimum/ typical) values for the studied tube geometry. In addition, the yield strength for the corresponding tempers (382 MPa for T3510 and 481 MPa for T8510) surpass any reported value in the literature or the highest industrial value. The ductility (% elongation) is also improved due the microstructural refinement and enhanced dispersion of precipitates by the solid phase processing followed by cold working in different temper conditions. |
