Abstract
a invenção ? refere-se a um processo de fabricação de um produto corroído, no qual: a) ? funde-se uma forma bruta em liga de alumínio de uma composição, em % em peso: mg: 4,0 ? 5,0; li: 1,0 -1,8; mn: 0,3 ? 0,5; zr: 0,05 ? 0,15; ag: < 0,5; fe: < 0,1; ti: < 0,15; si: < 0,05; outros elementos < 0,05 cada um e < 0,15 em associação restante alumínio; b) opcionalmente, ? homogeneiza-se essa forma bruta; c) ? deforma-se a quente essa forma bruta para se obter um produto deformado a quente; d) opcionalmente, se coloca em solução esse produto deformado a quente a uma temperatura de 360oc a 460oc, preferencialmente de 380oc - 420oc, durante 15 minutos a 8 horas; e) ? tempera-se esse produto deformado a quente; f) opcionalmente, ?efetua-se uma correção ou um aplainamento desse produto deformado e temperado; g) ? realiza-se um rendimento desse produto deformado e temperado; h) ? deforma-se a frio, de forma controlada, o produto deformado a quente, assim rendimento para obter-se uma deformação permanente a frio de 1 a 10%, de preferência, de 2 a 6% mais preferencialmente ainda de 3 a 5%. a invenção tem ainda por objetos um produto corroído capaz de ser obtido, de acordo com o processo da invenção assim como a utilização desse produto corroído para fabricar elementos de estrutura de aeronaves.the invention? refers to a process of manufacturing a corroded product in which: a)? an aluminum alloy crude form of a composition by weight% mg: 4.0? 5.0; li: 1.0 -1.8; mn: 0.3? 0.5; zr: 0.05? 0.15; ag: <0.5; fe: <0.1; ti: <0.15; si: <0.05; other elements <0.05 each and <0.15 in remaining aluminum combination; b) optionally,? this gross form is homogenized; ç) ? this raw form is hot deformed to obtain a hot deformed product; d) optionally, this hot-deformed product is placed in solution at a temperature of from 360 ° C to 460 ° C, preferably from 380 ° C - 420 ° C for 15 minutes to 8 hours; and) ? this hot deformed product is seasoned; f) optionally, correcting or flattening this deformed and tempered product; g)? a yield of this deformed and tempered product is realized; H) ? cold deforming the hot deformed product in a controlled manner, thereby yielding to obtain a permanent cold deformation of 1 to 10%, preferably 2 to 6%, more preferably 3 to 5%. The invention further relates to a corroded product obtainable in accordance with the process of the invention as well as the use of such corroded product to manufacture aircraft frame elements.
