Abstract: A method of producing an integrated monolithic aluminum structure, the method including the steps of: (a) providing an aluminum alloy plate with a predetermined thickness of at least 3 mm, wherein the aluminum alloy plate is a 2xxx-series alloy provided in an F-temper or an O-temper; (b) optionally pre-machining of the aluminum alloy plate to an intermediate machined structure; (c) high-energy hydroforming of the plate or optional intermediate machined structure against a forming surface of a rigid die having a contour in accordance with a desired curvature of the integrated monolithic aluminum structure, the high-energy hydroforming causing the plate or the intermediate machined structure to conform to the contour of the forming surface to at least one of a uniaxial curvature and a biaxial curvature; (d) solution heat-treating and cooling of the high-energy hydroformed structure; (e) machining and (f) ageing of the final integrated monolithic aluminum structure.

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.
