METHOD FOR MAKING STRUCTURAL ELEMENTS BY MACHINING THICK PLATES

The invention concerns a method for making a machined metal part comprising making a metal plate, pre-machining said plate on one or both sides to obtain a pre-machined blank, solution heat-treating said pre-machined blank, hardening, optionally followed by controlled traction. Such a part can be us...

Beschreibung
Zusammenfassung:	The invention concerns a method for making a machined metal part comprising making a metal plate, pre-machining said plate on one or both sides to obtain a pre-machined blank, solution heat-treating said pre-machined blank, hardening, optionally followed by controlled traction. Such a part can be used as structural element in aeronautics. L'invention concerne un procédé de fabrication d'une pièce métallique usinée, comportant la fabrication d'une tôle métallique, le préusinage de ladite tôle sur l'une ou les deux faces pour obtenir une ébauche préusinée, un traitement de mise en solution de ladite ébauche préusinée, un traitement de trempe, éventuellement suivi d'une traction contrôlée. Une telle pièce peut être utilisée comme élément de structure en construction aéronautique.
