Abstract

resumo "método de fabricação de elemento de aço formado em prensa a quente" a presente invenção refere-se a um método de fabricação de um elemento de aço formado em prensa a quente que tem altas resistências, um excelente equilí-brio entre resistência e ductilidade, e boas propriedades de deformação após esma-gamento em colisão (proteção à colisão). o método de fabricação é altamente efici-ente e permite um alto grau de liberdade com relação à forma a ser formada. o mé-todo fabrica um elemento de aço ao aquecer uma folha de aço tendo uma composi-ção química específica e ao submeter a folha de aço a pelo menos uma vez de for-mação em prensa a quente. no método, a temperatura de aquecimento é igual ou maior que a temperatura de transformação ac3, e uma temperatura inicial de forma-ção em prensa a quente se encontra na faixa da temperatura de aquecimento para a temperatura inicial de formação de martensita (ms). o resfriamento da [(temperatura ms) - 150°c] para 80°c é realizado de modo que um parâmetro de têmpera (?) especificado pela expressão (1) fique na faixa de 7100 a 8030.
