الملخص

AA6061 alloy is highly suitable for industries that prioritize weight reduction, including aerospace, automotive, and sporting goods. Its advantageous blend of lightweight characteristics and robust strength enables the creation of lightweight components and structures while preserving overall strength and performance. In this study, AA6061-T4 alloy chips were recycled using hot extrusion followed by room temperature ECAP. The effects of different numbers of passes and routes on the mechanical properties were investigated using ECAP die with 90° and 20° angles. Two routes, BC and C, were examined, the results showed significant improvements in the properties of the recycled chips after hot extrusion and ECAP processes. After four passes, maximum ultimate tensile strengths of 265 and 238 MPa, maximum yield strengths of 149 and 136 MPa, and elongation to failure of 46 and 41% were achieved for routes BC and C, respectively. Each pass increased yield strength, ultimate tensile strength, and hardness, while also increasing elongation to failure for routes BC and C. The mechanical properties of the ECAPed specimens were found to be higher than those of the extruded specimens. The number of passes and routes had a substantial impact on the mechanical properties and microstructures of the solid-state recycled AA6061-T4 alloy chip samples. SEM images revealed a honeybee-type pattern following ECAP through route BC, indicating the final mechanism of grain refinement and a mixed brittle-ductile fracture in the initial sample. These findings are consistent with other experimental results, demonstrating the effectiveness of the parameters and their impact on improving the mechanical properties.
