Supercooling during crystallisation and thermal dispergation of thin In-Pb films located between molybdenum layers

In this work, we study the supercooling during crystallisation of layers of fusible In-Pb alloys located between molybdenum layers. Two independent methods were used: electrical resistance measuring of the layered films, and electron diffraction during in situ heating and cooling. The concentration dependence of relative supercooling was obtained for Mo/(In-Pb)/Mo films, and it was found that this reached a maximum for samples containing about 50 wt.% of lead in a fusible alloy. The changes in the morphological structure of the films in the first heating cycle were studied using transmission and scanning electron microscopy, and it was found that melting did not significantly affect the morphological structure of Mo/(In-Pb)/Mo films, while (In-Pb)/Mo films underwent significant changes.
