Some characteristics of the crystallization of a liquid formed by contact melting

The crystallization of a liquid formed by the contact melting of adjacent thin films and that of a liquid flowing from the junction between cylindrical samples of Sn-Bi, Cd-Bi, and Sn-Pb alloys are studied. The structure of the crystallized layer is determined by x-ray microradiography. The liquid phase formed by contact melting is inho-mogeneous in composition even for a melting point close to the eutectic value. The concentration of the liquid so formed may vary according to whether the pure components or their solid solutions are in contact. Computed thermodynamic data are presented in support of this.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 8, pp. 7–12, August, 1971.The author wishes to thank Doctor of Technical Sciences Professor Il'e vasil'evich Saili for direction and help in discussing the results.
