Zusammenfassung:	The invention relates to a metal core (20) for high-temperature shaping of a metal part made of titanium-based alloy. The metal core (20) has a layer of material enriched in metal carbonitride on an outer surface (23) intended to come into contact with the metal part. The metal core (20) comprises an alloy based on nickel or cobalt. The metal core (20) comprises a steel coating (20B) having an outer surface (23) which is intended to come into contact with the metal part, the steel coating (20B) having a layer of material enriched in metal carbonitride (24). The invention also relates to processes for manufacturing and regenerating the metal core (20) and to a process for the high-temperature shaping of a metal part using the metal core (20). L'invention concerne un noyau métallique (20) pour conformation à chaud d'une pièce métallique en alliage à base de titane. Le noyau métallique (20) présente sur une surface extérieure (23), destinée à venir en contact avec la pièce métallique, une couche de matériau enrichi en carbonitrure métallique. Le noyau métallique (20) comprend un alliage à base de nickel ou de cobalt. Le noyau métallique (20) comprenant un revêtement en acier (20B) comportant une surface extérieure (23) destinée à venir en contact avec la pièce métallique, le revêtement en acier (20B) présentant une couche de matériau enrichi en carbonitrure métallique (24). L'invention concerne également des procédés de fabrication et de régénération du noyau métallique (20) ainsi qu'un procédé de conformation à chaud d'une pièce métallique utilisant le noyau métallique (20).
