Исследование структуры внутренней границы раздела фаз в ячейке реперной точки затвердевания индия

Abstract

The influence of the initiation method of inner liquid-solid interface in a cell of In fixed point on interface structure and the measured value of freezing temperature have been studied. The estimations of heat flux density by different methods of the inner liquid-solid interface initiation are received. Conditions of the optimum initiation for the exception of undesirable thermal communications between the thermometer well and cell walls are defined.
