Abstract

"AçO-CARBONO LIGADO E PROCESSO PARA FABRICAR UM AçO-CARBONO LIGADO, TENAZ, RESISTENTE à CORROSãO, DE ALTA RESISTêNCIA". Aços-carbono de elevado desempenho são descritos os quais contêm uma microestrutura de fase tripla consistindo de grãos de ferrita (11) fundidos com grãos que contêm estruturas de ripa deslocada na quais as ripas de martensita (13) alternam com filmes finos de austenita (14). A estrutura inclui os grãos de ferrita (11) fundidos com grãos de martensita-austenita (12), e cada um dos grãos de martensita-austenita (12) é da estrutura de ripa deslocada, com ripas substancialmente paralelas (13) consistindo de grãos de cristais de fase de martensita, as ripas separadas por filmes finos (14) de fase de austenita retida. A microestrutura pode ser formada por um método incomum de austenitização seguido por resfriamento de multifases em uma maneira que evita a formação e a precipitação de bainita e de perlita em interfaces de fases. A microestrutura desejada pode ser obtida por fundição, tratamento térmico, laminação em linha, forjamento, e outros procedimentos de processamento metalúrgico comuns, e dá combinações superiores de propriedades mecânicas e de corrosão.
