The invention concerns a method for producing parts made of thin, light and rigid metal alloy essentially comprising the following steps: producing a core (2) having the part (1) shape; producing cavities (4) in said core; producing skins (10) made of metal alloy combined with reinforcing fibres with high modulus of elasticity; densifying the skins (10); diffusion welding of said skins (10) on the core (2) by compression at temperature and pressure conditions for isothermal forging of the metal alloy used.
L'invention propose un procédé de réalisation de pièces en alliage métallique mince, légères et rigides comportant essentiellement les opérations suivantes: réalisation d'une âme (2) à la forme de la pièce (1), réalisation de cavités (4) dans ladite âme (2), réalisation de peaux (10) en composite alliage métallique + fibres de renfort à haut module d'élasticité, densification des peaux (10), soudage-diffusion desdites peaux (10) sur l'âme (2) par compression aux conditions de température et de pression de forgeage isotherme de l'alliage métallique employé.
