چکیده
|
In this paper,the surface tension of liquid au-bi-sn alloys has been calculated using kohler and toop models. in addition,the surface tension of the au-bi-sn ternary alloys over a wide temperature range (673-1273k) and their sub-binary systems are predicted on the basis of guggenheim equation. three selected cross-sections with the constant gold to bismuth ration of 1:1,1:2 and 2:1 have been studied. the results show that the surface tension increases with increasing tin and decreases with increasing temperature for the three studied models. the calculated values of the surface tension of the liquid au-bi-sn alloys at 673 k are compared with the experimental data available in literature. the best agreement is observed for the values obtained by guggenheim equation.
