Grain refinement, texture evolutions, and strengthening of a recycled aluminium alloy subjected to tube channel pressing

This works aims to study the grain refinement, the texture evolutions, and the strengthen-ing of the recycled Al-1.7Fe-0.9Si-0.5Cu alloy subjected to a recently developed severe plastic deformation process called tube channel pressing. For this purpose, an electron backscattered diffraction equipped scanning electron microscope is applied to investigate the grain refinement and the texture evolutions while the tension test is applied for the measurement of strength. Results show that the imposition of the first pass of the process causes an extensive refinement of grains besides a considerable increase in strength. Despite this, the imposition of additional passes causes a little grain refinement besides a minor strength decrease. Additionally, vital texture components related to the shear deformation have risen because of the imposition of the process. Also, the mechanisms responsible for these phenomena are discussed.

Automated summary

This study aims to investigate the grain refinement, texture evolutions, and strengthening of a recycled Al-1.7Fe-0.9Si-0.5Cu alloy using the tube channel pressing severe plastic deformation process. Electron backscattered diffraction equipped scanning electron microscope was used to analyze the grain refinement and texture evolutions, while tension test was conducted to measure the strength. The results show that the first pass of the process leads to significant grain refinement and strength increase, but additional passes only result in minor grain refinement and slight strength decrease. Moreover, important texture components related to shear deformation have been observed due to the process imposition.
