Abstract
Grain structure and mechanical properties of 6063 Al alloy subjected to one, two and three passes via combined rolling–ECAP at room temperature were investigated. The yield strength (196 MPa) and tensile strength (242 MPa) after three passes increased by 3.7 times and three times, respectively, relative to the initial annealed alloy (YS: 53 MPa, UTS: 82 MPa). Heat treatment comprising homogenizing annealing (600 °C, 15 min), water quenching from 520 °C and reheating to 100 °C before each pass led to ultrafine grains (600-800 nm) and high yield strength (245 MPa) and tensile strength (277 MPa). The three-pass combined rolling–ECAP process in conjunction with a suitable heat treatment is an effective way to form UFG structure and improved mechanical properties in 6063 Al alloy.
