Abstract

See full text

A method of producing an integrated monolithic aluminum structure, comprising: providing an aluminum alloy plate with a thickness of at least 38.1 mm, wherein the plate is a 2xxx-series alloy in a T3-temper and has a composition comprising, in wt. %: Cu 3.8-4.5, Mn 0.3-0.8, Mg 1.1-1.6, Si up to 0.15, Fe up to 0.20, Cr up to 0.10, Zn up to 0.25, Ti up to 0.15, Ag up to 0.10, balance aluminum; optionally pre-machining the plate to an intermediate machined structure; high-energy hydroforming the plate or intermediate structure against a rigid die forming surface having a desired curvature contour of the integrated monolithic aluminum structure, causing the plate or the intermediate structure to conform to the forming surface contour; machining or mechanical milling the high-energy formed structure to a near-final or final machined integrated monolithic aluminum structure; ageing the final integrated monolithic aluminum structure to a desired temper.
