Abstract
trata-se de um método para manufaturar uma chapa de aço de resistência alta que tem uma resistência à tração de mais de 1.100 mpa e um limite de escoamento de mais de 700 mpa, um alongamento uniforme ue de pelo menos 8,0% e um alongamento total de pelo menos 10%, feita de um aço que contém na porcentagem em peso: 0,1% = c = 0,25%, 4,5% = mn = 10%, 1% = si = 3%, 0,03% = al = 2,5%, em que o restante é fe e impurezas resultantes a partir da fundição, em que a composição se dá de modo que cmnindex = cx(1 + mn/3,5) = 0,6, sendo que o método compreende as etapas de recozer uma chapa laminada feita do dito aço embebendo-se a mesma a uma temperatura de recozimento ta mais alta que o ponto de transformação ac1 do aço, mas menor que 1.000 °c, resfriar a chapa recozida para uma temperatura de resfriamento brusco qt entre 190 °c e 80 °c a uma velocidade de resfriamento suficiente para obter uma estrutura logo após o resfriamento que contém martensita e austenita retida, manter a chapa de aço a uma temperatura de envelhecimento pt entre 350 °c e 500 °c por um tempo de envelhecimento pt de mais de 5 s e resfriar a chapa até a temperatura ambiente. a chapa é obtida.
