摘要
The temperature hysteresis of melting-crystallization in the layered film Al/Pb/Al system is revealed. The value of supercooling of Pb-based eutectic during its crystallization between Al layers is determined (as Delta T = 69 K) by electrical-resistance measurement during heating and cooling of a film Al/Pb/Al system. The value of Al-wetting angle (theta = 52 degrees) with lead-based eutectic particles is measured. The obtained results accord well with available data concerning dependence of relative supercooling value on a wetting angle of substrate with a crystallizing liquid.
