Abstract

L'invention concerne un procédé de fabrication de pièces à partir d'acier non-traité, comprenant une succession d'opérations de traitement thermique et de formage. Le procédé selon l'invention est caractérisé par les opérations successives suivantes: (a) chauffage d'austénitisation de l'acier à une température supérieure au point de transformation; (b) trempe isotherme dans un bain à lit fluidisé, immédiatement à la suite du chauffage d'austénitisation, donnant à l'acier une structure bainitique; et (c) formage des pièces à tiède, Un tel procédé permet de réaliser à moindre coût des pièces de qualité équivalente voire supérieure à celle obtenue par les procédés usuels.
