Abstract:

The activities in Liquid Fe-Cu, Fe-Cr and Fe-Sn alloys have been determined by a modified transportation method at 1873 K. The activity coefficients can be calculated by a graphical integration of the following equation using the concentration ratios of the components in vapor and metal phases:
