Abstract

Surface tension and viscosity of liquid Cr-Fe-Ni alloys were measured by means of the oscillating drop method using the electromagnetic levitation facility TEMPUS. Experiments were carried out under microgravity achieved during a parabolic flight of an airplane. The obtained surface tensions agree well with those determined under gravity conditions although they are found slightly smaller. The obtained viscosities exhibit very good agreement with corresponding data measured by the oscillating cup method confrming the accuracy of the obtained data through both techniques. Thermodynamic model calculations agree with our experimental fndings.
