The article presents data on combined anodic dissolution of aluminum alloy of Al–Li–Cu system with not high sensibility to intergranular corrosion, consisting in sequential dissolution in two different solutions, with different modes – the ratio of the specific amount of electricity. The obtained corrosion deteriorations were evaluated by optical and confocal microscopy, the dependences of mass loss, the depth of pitting and intergranular corrosion, as well as changes in the tensile strength of the specific amount of electricity for different modes were determined. As a result of the analysis of the obtained data, models for predicting the loss of tensile strength from the value of the specific amount of electricity (or mass loss) in atmospheric corrosion are proposed.

Abstract URANUS S1 is the development of 15 years research into alloys containing high silicon contents (4% here) to resist the transpassive intergranular corrosion from such chemicals as concentrated nitric acid. This datasheet provides information on composition, physical properties, elasticity, tensile properties, and shear strength. It also includes information on high temperature performance and corrosion resistance as well as forming, heat treating, and joining. Filing Code: SS-751. Producer or source: Cruesot-Marrel.
