Abstract

"PROCESSO PARA APERFEIçOAR LIGAS 6XXX POR REDUçãO DOS SìTIOS DE DENSIDADE ALTERADA". Processo para aperfeiçoamento das ligas 6XXX, tais como, 6013, preferivelmente incluindo aquecimento, laminação a quente, tratamento térmico de inter-laminação, em uma temperatura muito alta, tal como, 549<198>C ou mais, novamente laminação a quente (com ou sem laminação a quente contínua subsequente ou laminação a frio ou ambas), tratamento por aquecimento da solução e envelhecimento artificial. O aquecimento inicial, inter-laminação, tratamento térmico e tratamento da solução, especialmente os dois últimos, são realizados em temperaturas muito altas, tais como, 554<198>C. Cada estágio de laminação a quente descrito produz redução substancial da espessura do metal. O produto de folha ou chapa aperfeiçoado possui uma ocorrência substancialmente reduzida de defeitos de densidade reduzida, revelados no exame de microscopia por varredura de elétron em ampliação de 500 vezes e exibe razão de desenvolvimento de rachadura por fadiga aperfeiçoada (reduzida), provendo uma vantagem em aplicações aeroespaciais tais como, revestimento de fuselagem, especialmente revestimento da barriga de fuselagem.
