Abstract: A process for manufacturing a bimetallic part by means of a first component formed by a first aluminum alloy and a second component formed by a second aluminum alloy, said process involving: assembling the first component and the second component to obtain an assembled part; applying a thermal treatment to the assembled part at a temperature of 100 to 250° C., the thermal treatment causing the assembled part to deform, in particular as a result of a metallurgical deformation by a precipitation of hardening phases of the first component and/or the second component; cooling the part to ambient temperature, upon which the part remains deformed. The process involves, prior to the assembling step, an estimation of the degree of deformation that the assembled part will undergo under the effect of the thermal treatment.
