This thesis deals with the influence of deformation parameters on thestructure and mechanical properties of the alloy EN AW 6082. Two different semifinished products were compared - extruded semi-finished products and HCM semi-finished products. The structure and mechanical properties of these semifinished products in various variants of deformation and with or without heat treatment were evaluated. This thesis was created in cooperation with Strojmetal Aluminum Forging s.r.o.
