Abstract

"AçO DE BAIXA LIGA CONTENDO BORO". Um aço contendo boro, de resistência ultra-elevada, tendo uma resistência à tração de pelo menos cerca de 900 MPa (130 ksi - 9,14 tf/cm^ 2^), uma dureza como medida pelo ensaio de impacto de entalhe- V a -40°C (-40° F) de pelo menos 120 joules (90 libras-pé - 134 kg/m) e uma microestrutura compreendendo predominantemente bainita inferior finamente granulada, martensita mata-junta finamente granulada, ou misturas delas, transformado de grãos de austenita substancialmente não recristalizados e é preparado por aquecimento de uma chapa de aço em uma temperatura adequada; redução da chapa para formar placa em um ou mais passes de laminação a quente, em uma primeira faixa de temperatura em que a austenita recristaliza-se; mais redução de dita placa em um ou mais passes de laminação a quente, em uma segunda faixa de temperatura abaixo da dita primeira faixa de temperatura e acima da temperatura em que a austenita começa a transformar-se em ferrita durante o esfriamento (10); extinção (12) de dita placa a uma Temperatura de Parada de Extinção adequada (16); e parada de dita extinção e permissão para que dita placa esfrie ao ar (18) à temperatura ambiente.
