Abstract
Concentration dependence of activity a(c) in liquid Au-Gd alloys was measured at 1623 K by the Knudsen effusion method and reveals strong ordering effects. The percolation theory is proposed for analysis and calculation of activity data using concentration correlation function S{sub cc}(0) for several metallic solutions with chemical short range ordering (CSRO). The basic equations take into account the concentration difference factor c-c{sub 0} where c{sub 0} is the mean concentration at which the percolation threshold and maximum CSRO exist. The theoretical calculations of a(c) from given S{sub cc}(0) and vice versa are in satisfactory agreement with experimental data. The percolation theory was shown to be suitable for correct interpretation and prediction of activity and S{sub cc}(0) data in ordered melts. (orig.)
