Abstract

"PLACA DE AçO, E, PROCESSOS PARA PREPARAçãO DA MESMA, E PARA OBTER UMA TEMPERATURA DE TRANSIçãO DE DúCTIL PARA QUEBRADIçO (DBTT) MENOR DO QUE APROXIMADAMENTE -73°C NA ZONA AFETADA PELO CALOR (HAZ) DA PLACA DE AçO" Um aço de liga leve, de resistência ultra-elevada, soldável, contendo menos do que 9 % em peso de níquel, com excelente firmeza à temperatura criogênica na placa base e na zona afetada pelo calor (HAZ) quando soldado, tendo uma força de tração maior do que 830 MPa e uma microestrutura composta predominantemente de martensita ripada granulada fina e/ou bainita inferior granulada fina, é preparado pelo aquecimento de uma chapa de aço contendo ferro e alguns ou todos os aditivos carbono, manganês, níquel, nitrogênio, cobre, cromo, molibdênio, silício, nióbio, vanádio, titânio, alumínio, e boro; redução da chapa para formar placa em uma ou mais passagens em uma faixa de temperatura na qual a austenita recristaliza; laminação de acabamento da placa em uma ou mais passagens em uma faixa de temperatura abaixo de temperatura de recristalização e acima da temperatura de transformação Ar~ 3~; esfriamento rápido da placa laminada de acabamento (10''') até uma temperatura de Parada da Têmpera: parada do esfriamento rápido; e têmpera da placa (10''') em uma temperatura adequada por um período de tempo suficiente para provocar a precipitação de partículas de endurecimento.
