Disclosed herein is a method of forming a high strength aluminum alloy. The method comprises heating an aluminum material to a solutionizing temperature for a solutionizing time such that the magnesium and zinc are dispersed throughout the extruded aluminum material to form a solutionized aluminum material. The method includes quenching the solutionized aluminum material to form a quenched aluminum material. The method also includes aging the quenched aluminum material to form an aluminum alloy, then subjecting the aluminum alloy to an ECAE process to form a high strength aluminum alloy.

ECAE materials for high strength aluminum alloys

A method of forming a high strength aluminum alloy. The method comprises subjecting an aluminum material containing at least one of magnesium, manganese, silicon, copper, and zinc at a concentration of at least 0.1% by weight to an equal channel angular extrusion (ECAE) process. The method produces a high strength aluminum alloy having an average grain size from about 0.2 &#x3bc;m to about 0.8 &#x3bc;m and a yield strength from about 300 MPa to about 650 MPa.
