Based on the analysis of experimentally established phenomena related to the behavior of hydrogen in melts and castings, a model of hydrogen distribution in liquid aluminum alloys has been proposed, based on the presence of two forms of hydrogen: lightly mobile in a disordered zone and less mobile in solid-gascluster complexes.
