Abstract: A method is provided for forming complex structures from aluminum alloys, particularly from naturally hard AlMg alloys, naturally hard AlMgSc alloys and/or age-hardenable AlMgLi alloys. The method, in a simple manner by means of as few process steps as possible, forms complex structures from the alloys such that they almost assume their final shape without any significant spring-back. Simultaneously, the loss of material is to be kept as low as possible. This is achieved by means of the following steps: elastic forming of a component to be formed into a defined contour under the effect of external force; and heating-up of the elastically formed component to a temperature higher than the temperature required for a creep formation and relaxation of stresses of the alloy, so that the component is formed while retaining the contour.

It is an object of the invention to provide such a method by means of which, in a simple manner, that is, by means of as few process steps as possible, complex structures can be formed from the alloys according to the invention such that they almost assume their final shape without any significant spring-back. Simultaneously, the loss of material is to be kept as low as possible.
