Abstract

"PEçA DE ALTA RESISTêNCIA E MéTODO DE PRODUçãO DA MESMA". Uma peça de alta resistência que excede em resistência à fragilidade pelo hidrogênio e resistência após a conformação a alta temperatura; e um processo para produção da mesma. A atmosfera em um forno de aquecimento antes da conformação é regulada para um entre <243> 10% em volume de hidrogênio e <243> 30 C de ponto de orvalho. Como resultado, a quantidade de hidrogênio que penetra em uma chapa de aço durante o aquecimento é reduzida. Após a conformação, são executados sequencialmente o resfriamento, o endurecimento no conjunto do molde e o trabalho posterior. Como método de trabalho posterior, podem ser mencionados o aparamento seguido de reaparamento ou conformação por compressão da porção da borda aparada; puncionagem com uma lâmina de corte tendo uma porção gradiente na qual a largura da base da lâmina é continuamente reduzida; puncionagem com uma ferramenta perfuradora tendo uma lâmina curva com uma configuração protuberante na ponta da lâmina de corte, a lâmina curva tendo uma porção de ombro com um dado raio de curvatura e/ou um dado ângulo; corte por fusão; etc. Consequentemente, o estresse residual de tensão após o puncionagem é reduzido e a perfomance da resistência à fragilidade pelo hidrogênio é melhorada.
