Temperature Limits of the Existence of the Liquid Phase of Bismuth Particles that are in Contact with Nanocrystalline Vanadium Films

With the use of two independent in situ methods, the crystallization temperature of supercooled bismuth in a Bi/V contact pair was measured. It was shown that the condensation mechanism of the fusible component does not affect the achieved supercooling value, which is somewhat higher than 0.3 of the melting point. However, the temperature width of the crystallization range in the samples obtained by the condensation through the vapor-crystal mechanism is larger than in those obtained using the vapor-liquid condensation mechanism. The observed peculiarities are explained by the interrelationship between the morphology and the mechanism of condensation of the samples.
