Abstract
A method of producing an integrated monolithic aluminum structure including providing an 7xxx-series aluminum alloy plate with a predetermined thickness of at least 10 mm, and wherein the plate has been solution heat treated and stretched, heat-treating the plate product in a first of a plurality of artificial ageing steps required to achieve a final temper state, high-energy hydroforming the plate against a forming surface of a rigid die having a contour with a desired curvature of the integrated monolithic aluminum structure, the high energy forming causing the aluminum alloy plate to conform to the forming surface contour to at least one of a uniaxial curvature and a biaxial curvature, heat-treating the integrated monolithic aluminum structure through a remaining ageing step of the ageing steps to achieve a desired final temper, and machining the high-energy formed structure to a near-final or final machined integrated monolithic aluminum structure.
