Special Features of Nucleation and Growth of Tin Crystals in the Temperature Range of Its Polymorphic Transformation

Special features of nucleation and growth of tin whiskers in the range of tin polymorphic transformation on galvanically tin-plated surfaces of parts of electric devices and laboratory specimens in the absence of the action of electric fields and moisture are considered. The main factors responsible for the nucleation and growth of crystals are determined. Process and maintenance recommendations are given for deceleration of formation of crystals in the period of storage and service of devices.
