Abstract

trata-se de um método de fabricação de uma folha de alta resistência que tem uma segregação de formabilidade aperfeiçoada de acordo com a qual a composição química do aço contém, em porcentagem em peso: 0,1% = c = 0,4% 4,2% = mn = 8,0% 1% = si = 3% 0,2% = mo = 0,5% em que o restante é fe e impurezas inevitáveis, sendo que o método compreende as etapas de realizar o recozimento de uma folha laminada produzida a partir do dito aço embebendo-se o mesmo a uma temperatura de recozimento at maior que o ponto de transformação ac3 do aço, resfriar bruscamente a folha resfriando-se a mesma até uma temperatura de resfriamento brusco qt entre os pontos de transformação ms e mf a fim de se obter uma estrutura final que contenha pelo menos 65% de martensita e pelo menos 20% de austenita residual, sendo que a soma dos teores da ferrita e da bainita é menos que 10%, aquecer a folha até uma temperatura de sobre-envelhecimento pt entre 300 °c e 500 °c e manter a mesma na dita temperatura por um pt maior que 10 s, e resfriar a folha até a temperatura ambiente. obtendo-se a folha.
