Abstract: The present invention relates to the method of fabrication of wrought semiproducts from high strength aluminium-based alloys, and fabrication of articles from such semiproducts e.g frames, fittings, beams, etc. used in aerospace engineering and transportation facilities. The suggested method comprises: casting an ingot, homogenization, forging the ingot, extrusion of the wrought billet, solution heat treatment, cold working in two steps: 1. stretching with 1-5% permanent set, 2. multi-axial shaping of the billet by bending while simultaneously performing the local plastic deformation of the billet by compressing (1-20%) the joint places of the blank parts being disposed at an angle of 45-135° to each other; two stage ageing: 1st stage=heating to 90-120° C. for 5-24 hours; 2nd stage=heating to 160-190° C. for 5-20 hours.
