The present invention relates to a method of forming complex structures fro m aluminum alloys, particularly from naturally hard AlMg alloys, naturally har d AlMgSc alloys and/or age-hardenable AlMgLi alloys. 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-bac k. Simultaneously, the loss of material is to be kept as low as possible. According to the invention, this is achieved by means of the following steps: Elastic forming of a component (1) to be formed into a defined contour (2a) under the effect of external force (F,P, p); and heating-up of the elastically formed component (1) to a temperature (Ti) higher than the temperature required for a creep formation and relaxation of tensions of the alloy, so that the component (1) is formed while retaining the contour (2a).
