Abstract
La présente invention concerne un procédé de fabrication d'une pièce revêtue durcie à la presse consistant à utiliser un four comprenant n zones, chaque zone du four étant respectivement chauffée à une température de réglage t1f, t2f, tif,..., tnf, à mettre en œuvre les étapes successives suivantes consistant à : utiliser une tôle d'acier d'une épaisseur th comprise entre 0,5 et 5 mm, comprenant un substrat en acier recouvert d'un prérevêtement en alliage d'aluminium d'une épaisseur comprise entre 15 et 50 µm, le coefficient d'émissivité étant égal à 0,15(1 + a), a étant compris entre 0 et 2,4, puis découper ladite tôle d'acier pour obtenir une ébauche d'acier prérevêtue, puis placer l'ébauche d'acier prérevêtue dans la zone 1 du four pendant une durée ti comprise entre 5 et 600 s, tif et t1 étant tels que : t1fmax > t1f > t1fmin, avec : t1fmax =(598 + a ebt1 + cedt1) et t1fmin = (550 + a' eb't1 + c'ed't1), et a, b, c, d, a', b', c, d' étant tels que : a = (762 e0,071 th - 426 e-0,86 th) (1 - 0,345a), b = (-0,031 e-2,151 th - 0,039 e-0,094 th) (1 + 0,191a), c = (394 e0,193 th - 434,3 e-1,797 th) (1 - 0,364a), d = (-0,029 e-2,677 th - 0,011 e-0,298 th) (1 + 0,475a), a' = (625 e0,123 th - 476 e-1,593 th) (1 - 0,345a), b' = (-0,059 e-2,109 th - 0,039 e-0,091 th) (1 + 0,191a), c' = (393 e0,190 th - 180 e-1,858 th) (1 - 0,364a), d' = (-0,044 e-2,915 th - 0,012 e-0,324 th) (1 + 0,475a), t1f, t1fmax et t1fmin étant en ° celsius, t1 étant en s., et th étant en mm, puis transférer l'ébauche d'acier prérevêtue dans la zone 2 du four chauffée à une température de réglage t2f = t1? Et maintenir de manière isotherme l'ébauche d'acier prérevêtue pendant une durée t2, t2f et t2 étant tels que : t2min = t2 = t2max avec : t2min = 0,95 t2* et t2max = 1,05 t2* avec : t2* = t1 2 (-0,0007 th2 + 0,0025 th - 0,0026) + 33 952 - (55,52 x t2f), t2f étant en ° celsius, t2, t2min, t2max, t2* étant en s., et th étant en mm, puis transférer l'ébauche d'acier prérevêtue dans d'autres zones (3, ...I, ..., n) du four, de façon à atteindre une température d'ébauche maximale tmb comprise entre 850 °c et 950 °c, la vitesse de chauffage moyenne va de l'ébauche entre t2f et t?? étant comprise entre 5 et 500 °c/s, puis transférer l'ébauche d'acier chauffée du four dans une presse, puis former à chaud l'ébauche d'acier chauffée dans ladite presse de façon à obtenir une pièce, puis refroidir la pièce à une vitesse de refroidissement afin d'obtenir une microstructure dans le substrat en acier comprenant au moins un constituant choisi parmi la martensite ou la bainite.
