Abstract
métodos de formação a frio de ligas de alumínio lítio. a presente invenção refere-se a métodos de produção de ligas de alumínio lítio extrudado formadas a frio e produtos não recristalizados feitos a partir das mesmas. um método pode incluir um ou mais dentre aquecer um produto de alumínio lítio extrudado não recristalizado a uma temperatura de tratamento, resfriar o produto de alumínio lítio extrudado não recristalizado a partir da temperatura de tratamento até uma temperatura de pós-tratamento e formar a frio o produto de alumínio lítio extrudado não recristalizado em uma segunda forma de produto. devido às condições de processamento exclusivas do método, a segunda forma de produto pode reter total ou parcialmente a microestrutura não recristalizada.
