Review of data for the surface tension of iron and its binary alloys

Abstract

A review has been conducted of the literature data pertaining to the surface tensions of pure iron and iron binary alloys. Approximate values for the respective surface activities of the alloying elements have been deduced. Of particular note are the high surface activities exhibited by Group VI elements in iron, together with the positive temperature coefficients of surface tension found with these alloys. Literature data for the suggested surface structures of the melts, based upon adsorption measurements, are included in this review.
