Abstract
trata-se de um método de processamento de chapa de aço bifásico. o método inclui o aquecer a chapa de aço a uma primeira temperatura (t1), o resfriar a chapa de aço a uma segunda temperatura (t2), a transição da temperatura da chapa de aço para uma terceira temperatura (t3), e o resfriar a chapa de aço à temperatura ambiente. t1 é ao menos maior que a temperatura na qual a chapa de aço se transforma em austenita e ferrita. t2 é menor que a temperatura inicial da martensita (ms). a taxa de resfriamento até t2 é suficientemente rápida para transformar ao menos um tanto de austenita em martensita.
