Abstract
trata-se de um método para fabricar um produto de aço que compreende as etapas de: fornecer um produto de partida de aço aquecido a uma temperatura que compreende entre 380 °c e 700 °c, que tem uma estrutura metaestável completamente austenítica, com uma composição que compreende, em porcentagem de peso: 0,15% = c = 0,40%,1,5% = mn = 4,0%, 0,5% = si = 2,5%, 0,005% = al = 1,5%, com 0,8% = si+al = 2,5%, s = 0,05%, p = 0,1%, pelo menos um elemento escolhido dentre cr e mo, de modo que: 0% = cr = 4,0%, 0% = mo = 0,5% e 2,7% = mn + cr + 3 mo = 5,7% e, opcionalmente, um ou diversos elementos escolhidos dentre: nb = 0,1%, ti = 0,1%, ni = 3,0%, 0,0005% = b = 0,005%, 0,0005% = ca = 0,005%, sendo que o saldo da composição consiste em ferro e impurezas inevitáveis que resultam da fundição; submeter o dito produto de partida a uma etapa de conformação a quente a uma temperatura que compreende entre 700 °c e 380 °c, com uma deformação acumulada ¿b entre 0,1 e 0,7, em pelo menos um local do dito produto de partida de aço aquecido, para obter um produto de aço formado a quente completamente austenítico; então, arrefecer bruscamente o produto de aço formado a quente através de resfriamento do mesmo, a uma taxa de resfriamento vr2 superior à taxa de resfriamento martensítico crítica, para uma temperatura de arrefecimento brusco qt inferior a ms de modo a obter uma estrutura que contém entre 40% e 90% de martensita, sendo que o resto da estrutura é austenita; então, manter em, ou reaquecer o produto até uma temperatura de retenção pt entre qt e 470 °c e reter o mesmo na dita temperatura pt por uma duração pt entre 5 s e 600s.
