Abstract

Procédé de forgeage d’une pièce en acier maraging L’invention concerne un procédé de forgeage d’une pièce à partir d’un lingot d’acier maraging caractérisé en ce qu’il comprend trois étapes : - une première étape de forgeage du lingot réalisée à une vitesse rationnelle de déformation inférieure à 1 s-1 jusqu’à une déformation supérieure ou égale à 1 à une température comprise entre 1150°C et 1250°C ; suivie - d’une deuxième étape de forgeage réalisée à une vitesse rationnelle de déformation inférieure à 1 s-1 jusqu’à une déformation inférieure ou égale à 2, réalisée à une température inférieure à la première étape ; suivie - d’une troisième étape de forgeage réalisée à une vitesse rationnelle de déformation supérieure ou égale à 1 s-1 et jusqu’à une déformation comprise entre 0,5 et 2.
