Abstract
This works aims to study the grain refinement, the texture evolutions, and the strengthening 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.

Key words
