Tensile strength and deformation microstructure of Al–Mg–Si alloy sheet by through-width vibration rolling process

This work explored a novel severe plastic deformation scheme, through-width vibration rolling, to continuously produce high-strength aluminum sheet. As-processed AA6061 (Al–Mg–Si) alloy sheet was directly subjected to ageing treatment, by which the yield strength up to 480 MPa and the ultimate tensile stress of 491 MPa could be obtained.
