Abstract
By making effective use of precipitation hardening of AA3004 alloys, a superstrengthening effect was achieved in the manufacturing of AA3004 can stock materials through modified processing, which combines a regular work hardening process with a further precipitation hardening process. The annealing operation in the conventional processing was replaced by a high-temperature solution treatment to regain a high supersaturation of solutes in solid solution. The combined operations of cold rolling and low-temperature aging were able to yield varied combinations of high mechanical strength and ductility. In this work, the effects of processing sequences on the mechanical property improvement and the texture control of the final gage sheets were studied. The mechanical properties of the materials were evaluated based on the tensile results. Texture analyses were performed by means of orientation distribution function (ODF) descriptions. Earing tests were carried out in order to determine the mechanical anisotropy of the final sheets.
