Beschreibung
Zusammenfassung:	A process for manufacturing a metal part such as a metal reinforcement for the blade of a turbine engine, comprising a step for manufacturing a three-dimensional metal structure made up of an insert which has properties which allow superplastic forming and diffusion welding to be carried out, and of multiple metal wires, each separate metal wire encircling a periphery of the insert, the metal structure forming a preform of the three-dimensional metal part; a step in which the three-dimensional metal structure is positioned in a forming tool; a hot-pressing step of the three-dimensional metal structure which causes agglomeration of the three-dimensional metal structure, so as to obtain the compact metal part. La présente invention concerne un procédé de réalisation d'une pièce métallique telle qu'un renfort métallique d'aube de turbomachine comportant successivement : une étape réalisation d'une structure métallique tridimensionnelle (310) constituée par un insert (301) présentant dans propriétés permettant le formage superplastique et le soudage diffusion et par une pluralité de fils métalliques (302) encerclant la périphérie dudit insert (301), ladite structure métallique (310) formant une préforme de ladite pièce métallique (30); une étape de positionnement de ladite structure métallique (310) dans un outillage de forme : une étape de pressage à chaud de ladite structure métallique tridimensionnelle (310) provoquant l'agglomération de ladite structure métallique (310) de manière à obtenir ladite pièce métallique compacte.
