Surface tension of liquid Fe-Ti alloys at 1823 K

摘要

Surface tension of liquid Fe-Ti alloys has been determined by using the constrained drop method at 1823 K in Ar-10 percent H_2 gas atmosphere. It was found that the surface tension of liquid Fe-Ti alloy decreases slightly with increasing titanium content. In addition, the surface tension of Fe-Ti alloy was also obtained by a theoretical calculation. It was found that the experimental results became slightly lower than the calculated results with increasing titanium content. This paper also discusses the possible reasons for the slight decrease in the surface tension with increasing the titanium content.
