Thermophysical characteristics of liquid metals and alloys at TU Graz: a status report
G. Pottlacher, K. Aziz and A. Schmon
Our work group has rendered outstanding services in the field of dynamic pulse calorimetry within the last thirty years to obtain thermophysical properties of liquid metals and alloys. Today, only few more experiments on pure metals are to be expected, because almost all metallic elements, which are suitable for our pulse-heating system so far, have been investigated. These elements are: C, Co, Cu, Al, Au, Hf, In, Ir, Fe, Pb, Mo, Ni, Nb, Pd, Pt, Re, Rh, Ag, Ta, Ti, W, V, Zn, and Zr. A summary of these results is given in . The investigations of different alloys will continue. To extend the range of thermophysical properties obtained in the liquid phase a levitation facility is set up right now within Austrian Science Fund (FWF) Project P 23838-N20 using parts of equipment obtained from DLR, Cologne, Germany. To access accurate data also in the solid phase we added a four point probe apparatus, and further a DSC as well as a DTA to our equipment.
