Origine de l’éclatement de grain sur des pièces forgées en Inconel 718

L'Inconel 718 est un superalliage base nickel très utilisé pour produire les disques de turboréacteurs. Typiquement, une gamme de forgeage à chaud se compose de plusieurs étapes de déformation et de recuit. La présence des particules de seconde phase (particules de phase delta dans l'Incon...
