Abstract

Procédé de fabrication d'un demi-produit en tôle adapté pour le formage à chaud, qui présente un meilleur rapport entre solidité et ductilité, demi-produit en tôle fabriqué selon ledit procédé et pièce fabriquée à partir de ce demi-produit en tôle, en particulier pièce pour carrosserie de véhicule automobile. Ledit procédé comporte les étapes suivantes : fabrication d'une matière de départ en acier revenu auquel sont ajoutés des éléments de microalliage en quantités prédéterminées, traitement de la matière de départ dans un train de laminage continu à chaud ou de laminage de coulée continue pour obtenir le demi-produit en tôle, traitement de la matière de départ d'abord à une température se trouvant dans la plage de la température de dissolution des éléments de microalliage, refroidissement de la matière de départ jusqu'à une température située au-dessous de la température de précipitation (TAUSS) pour précipiter au moins une partie des éléments de microalliage, laminage de la matière de départ pour former le demi-produit en tôle et commande de la température et des intervalles de temps dans diverses zones de laminage et éventuellement ensuite de manière telle que le demi-produit fini présente une grande finesse des grains et un degré de recristallisation (α ± RX) présélectionné.
