用卧滴法测定了液态Pb,Sb纯金属和Pb-Sb合金熔体的表面张力,其表面张力的温度系数均为负值。在同一温度下Pb-Sb熔体的表面张力值介于两纯金属值之间,其值随成分星非线性变化,且对“理想溶液”为负偏差。对液态二元共晶型合金,本文提出“液态类共晶原子团”的概念,并依此解释液态二元共晶型合金的表面张力现象。
Measurements of the surface tension of the Pb-Sb binary melts were made by the sessile drop method. All the temperature coefficient of their surface tension was obtained in a negative quantity. At the same measuring temperature, the values of the surface tension of Pb-Sb melts lie between that of each pure component and vary non-linearly with their compositions which show a negative diviation from the "ideal solution". As the results of this liquid binary eutectic alloy, a concept of the "liquid similar eutectic atomic clusters" (LSEAC) may be approached by the authors to interpret the surface tension phenomena of the binary alloys of eutectic type.
