Abstract

''AçO PARA ESTIRAMENTO PROFUNDO DE ALTA RESISTêNCIA DESENVOLVIDA POR REAçãO COM AMÈNIA'' Um método para a produção de chapas de aço com elevada resistência e artigos moldados a partir de chapa e contendo cerca de 0,01-03 Ti, Ni ou V não combinados e livres de porcentagem atómica como elemento de reforço efetuando-se a termolaminação, ou termolaminação seguida de laminação a frio da placa dentro de faixas limitadas de temperatua, o efetuando-se o recozimento da chapa laminada ou artigos moldados a uma temperatura de cerca de 689°C-730°C (1275-1350°F) para prover uma estrutura de grão (111), nitrificar e chapa recozida ou artigo moldado em forno de recozimento a uma temperatura de cerca de 425-674°C (800-1250°F) sob fluxo de gás laminar ou turbulento e controlar a resistência do artigo de aço como uma função da composição do aço, da composição do gás de nitrificação, da temperatura de nitrificação, da espessura da chapa de aço e da profundidade de resisitência desejada, de acordo com relações especificadas, para prover um artigo de aço tendo um limite de elasticidade com 0,2% de distância após laminação de necruamento de pelo menos 15284kcm² (40ksi) e um valor r de cerca de 1,7 para a chapa laminada a frio.
