Отсутствие однозначной интерпретации экспериментального материала по модифицированию металлов и сплавов делает актуальным поиск и доказательство гипотез, выходящих за рамки классического физико-химического подхода. Предложена квантово-механическая теория модифицирующего влияния веществ, в частности оксидов BaO, SrO, CaO в составе природного модификатора БСК-2, на металлические свойства, дополняющая классическую теорию гетерогенного зародышевания твердой фазы. Единая природа модифицирующего влияния веществ, вибрации и ультразвука на металлический расплав связана с возникновением осцилляций Фриделя. С позиции физики контактной разности потенциалов показаны особенности процесса зародышеобразования в металлических расплавах. На основе теории свободных электронов объясняется модифицирующая способность ультрадисперсных включений.

The absence of unambiguous interpretation of experimental dataon the modifi cation of metals and alloys makes it relevant to search and prove hypotheses beyond the classical physical and chemical approach. The paper presents a quantum-mechanical theory of modifying infl uence of substances, in particular the oxides BaO, SrO, CaO in the composition of natural modifi er BSK-2 to metal properties, to complement the classical theory of heterogeneous nucleation of solids. The uniform nature of the modifying infl uence of substances, vibration and ultrasound on the molten metal is connected with the occurrence of the Friedel oscillations. The physics of the contact potential difference shows characteristics of the nucleation process in metal melts. The modifying ability of ultrafi ne inclusions is explained by the theoryof free electrons.
