Abstract

The maximum bubble pressure method was used for the measurement of the surface tension of liquid metals and alloys at high temperature. Fundamental problems of the measurement were discussed through the preliminary experiment prior to the measurement of surface tension of liquid Pb-Sn alloys. It is shown that the values of surface tension at Sn-26.1 at%Pb indicate a peculiar behavior in comparison with those of other compositions. This phenomenon may be attributed to the formation of cluster in the liquid.
