Justification of the surface mechanism of the metal melts stratification in capillaries and its communication with structure of liquid

N.P. Uglev

ABSTRACT:

Researches of structural change of the eutectic melts of tin with lead at their stratification in glass capillaries are conducted, in comparison with the exemplars which were not exposed to stratification. Noticeable structural change on height and radius of a capillary, and also the strong influence of duration of an experiment on the size and a form of building blocks of a melt is revealed. Experiments on stratification in a capillary in the form of a scroll, in a capillary with a nozzle, and also in flat capillaries, allowed to localize a stratification mechanism area of coverage in the field of the monoatomic surface layer of a fluid exemplar. Researches of structure of the melts received in various conditions allowed to assume that disolution of solid metal (lead) takes place in fluid (tin) due to eliminating of large units, but not separate atoms. The analysis of the given experiments, in total with literary data, allows to assume that liquid represents an ultracolloid system of the solid clusters separated from each other by a monoatomic film when which driving there is a process of a mass transfer both on height, and across a capillary.
