Argon absorption by a liquid metal with its fixation in a solid is studied. With the use of a low-temperature argon-containing plasma for metal melting, the solidified metal was produced, containing a considerable amount of argon (up to <$E 10 sup -3> wt.%), but having no additional pores, blowholes, and discontinuities, as compared to the same metal, where melting and solidification proceeded in the atmosphere containing <$E roman CO sub 2>. A significant simultaneous improvement of mechanical properties of the metal containing argon (strength, elongation, reduction in area, and impact toughness at negative temperatures of <$ -40~symbol Ш~-50~symbol Р>C) was found, which is preserved for a long time (years). Various investigation methods were used to demonstrate that а new kind of impurity element solid solutions, called alligator (or entrapment solid solution) is formed in the metal under the experimental conditions. The conditions for obtaining it, its features, and properties are determined.
