    摘要: 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.
