The surface tension of liquid Fe-Ti and Fe-C-Ti systems under hydrogen atmosphere has been determined by the sessile and pendent drop methods. The relative adsorption of titanium, as measured by −(dσ⁄dμTi)T,p, where σ is the surface tension and μTi the chemical potential of titanium, is 5.61×10−6 mol/m2 in the range from 0.2 to 33.3 at%Ti at 1823 K. Application of the monolayer approximation shows that the surface concentration of titanium increases linearly from 0.24 (mole fraction) at 0.2 at% to 0.5 at 33.3 at%. An evaluation of surface tension on the basis of model proposed by Laty by neglecting the gas phase could not represent the experimental results, because the surface activity of titanium was caused by the chemisorption of hydrogen.<BR>The experimental results for Fe-C-Ti alloys suggested the formation of compound TiC on the surface.
