<p>Fabrication of components of hardened structural aluminum alloy uses friction stir welding to assemble at least two elements of the same or different alloys, the putting into solution treatment and the hardening of the welded components. After welding the elements are subjected to heat treatment at a temperature T for a duration of at least 2t1, where t1 is defined as the minimal duration of a treatment at the temperature T leading to an energy specific for the peak of fusion, defined by differential enthalpy analysis, of less than 1 Joule/g. An Independent claim is also included for a component of at least two elements welded by this method.</p> |
