Abstract
L'invention concerne un procédé consistant à utiliser une feuille laminée à froid, ayant une composition contenant : 0,15 % = c = 0,23 %, 1,4 % = mn = 2,6 %, 0,6 % = si = 1,3 %, avec c + si/10 = 0,30 %, 0,4 % = al = 1,0 %, avec al = 6 (c+mn/10) – 2,5 %, 0,010 % = nb = 0,035 %, 0,1 % = mo = 0,5 %, à réaliser un recuit de la feuille à 860° c-900° c pour obtenir une structure constituée d'au moins 90 % d'austénite et d'au moins 2 % de ferrite intercritique, à tremper à une température comprise entre ms-0 °c et ms-60 °c à une vitesse vc supérieure à 30 °c/s, à chauffer à une température pt comprise entre 410 °c et 470 °c pendant 60s à 130s, à revêtir la feuille par immersion à chaud, et à refroidir à température ambiante. La microstructure comprend de 45 % à 68 % de martensite, constituée de 85 % à 95 % de martensite fractionnée ayant une teneur en c de 0,45 % maximum, et de martensite fraîche ; de 0 % à 15 % d'austénite résiduelle ; de 2 % à 10 % de ferrite intercritique ; de 20 % à 30 % de bainite inférieure.
