Essay

The thesis is devoted to investigation of stages, kinetic and thermodynamic parameters of cellular precipitation of supersaturated solid solutions for the whole range of homogeneous supersaturated solid solutions of tin in lead. X-ray analysis, hydrostatic weighing, optical microscopy methods and electrical resistance measurements were applied for those investigations. It was found that the process of precipitation from solid solutions occurs in two stages: primary and secondary cellular reactions. On the example of lead alloy with 14,73 at.% tin investigated the influence of cellular precipitation on the temperature superconducting transition in this alloy.
