Abstract

Patente de Invenção: <B>"PROCESSO PARA PRODUçãO DE UMA FOLHA DE LIGA DE ALUMìNIO"<D>. Uma folha de uma liga de alumínio lingotada continuamente e laminada tendo um teor de Mg de 3 a 6% em peso é recozida, seguida de uma correção de deformações, tratada com aquecimento e espera a uma dada temperatura entre 240°C e 340°C por uma hora ou mais, e tratada com resfriamento lento, para assim fornecer uma folha de liga de alumínio que tem uma resistência ao trincamento atribuído à corrosão sob tensão e uma fixação de forma melhorada. O tratamento de resfriamento lento é executado a uma taxa de resfriamento escolhida de uma zona de resfriamento pre-determinada correspondendo a uma zona de temperatura predeterminada S definida pela forma determinada pela linha oblíqua no desenho anexo.
