Abstract

L'invention concerne un procédé pour réaliser un composant trempé à la presse à partir d'un demi-produit en tôle d'acier non trempée pouvant être mise en forme à chaud, procédé selon lequel le demi-produit est chauffé puis trempé à la presse dans un outil de mise en forme à chaud. L'objectif de cette invention est d'augmenter les profondeurs d'emboutissage pouvant être atteintes lors de la trempe à la presse. A cet effet, la vitesse de mise en forme à laquelle le demi-produit est mis en forme dans l'outil de mise en forme à chaud est si élevée que le processus de transformation d'une structure austénitique en une structure martensitique ou bainitique n'est terminé qu'une fois le processus de mise en forme achevé. Avantageusement, cette vitesse de mise en forme est supérieure à 65 mm/s. Ladite invention concerne également un composant réalisé selon ledit procédé. Ce composant peut présenter un revêtement anticorrosion en matériau aluminium-silicium.
