Abstract

La invención trata con un proceso para fabricar una lámina de acero galvanizada o galvano-recocida por inmersión en caliente que tiene una microestructura TRIP, el proceso comprende los pasos que consiste en: - proporcionar una lámina de acero cuya composición comprende, en peso: 0.01 = C = 0.22 %, 0.50 = Mn 2.0%, 0.2%, 0.005 = Al = 2.0%, Mo < 1.0%, Cr = 1.0%, P 0.2%, Ti 0.2 =, V = 0.40%, Ni = 1-0%, Nb = 0.20%, el resto de la composición que es hierro e impurezas inevitables que resultan de la fundición, oxidar la lamina de acero en un horno de flama directa donde la atmósfera comprende aire y combustible con una relación de aire a combustible entre 0.80 y 0.95 de modo que una capa de cosido de hierro que tiene un espesor de 0.05 a 0.2 mum se forma sobre la superficie de la lamina de acero, y se forma un óxido interno de Si y/o Mn y/o Al, -reducir la lámina de acero oxidada, en una velocidad de reducción de 0.0001 a 0.10 mum/s, a fin de lograr una reducción de la capa de óxido de hierro, galvanizar por inmersión en caliente la lámina de acero reducida para formar una lámina de acero recubierta con zinc y opcionalmente, someter la lámina de acero recubierta por inmersión en caliente a un tratamiento de aleación para formar una lámanla de acero galvano-recocida.
