N2 - Aluminum alloys are very popular in a variety of technical applications. The strong influence of hydrogen on the properties of aluminum alloys is known, however, as in the case of steels; it is continuously increasing as new alloys with extreme properties are developed and introduced. Scientific research in the field of the hydrogen effect on the properties of aluminum alloys is mainly focused on the fundamental aspects such as the diffusion coefficients of hydrogen in aluminum, possible types of hydrogen traps, and their effect on the microstructure of alloys. At the same time, the industry has a problem of cracking ingots and semi-finished products (sheets, pipes, and plates), including their further processing and welding. In contrast to the high-strength steels, scientific research does not actually provide specific values for critical hydrogen concentration. The problem of separating the hydrogen adsorbed on the surface and dissolved during measurements has not been solved. There are only a few types of aluminum alloy reference specimens. The article is intended to partially fill this gap. It provides specific examples of the study of technological problems and proposes the measurement methods that allow the separation of hydrogen dissolved and adsorbed on the surface.
