INVESTIGATIONS OF THERMOPHYSICAL PROPERTIES OF LIQUID-METALS WITH A RAPID RESISTIVE HEATING TECHNIQUE

Wire-shaped metal samples are resistively pulse heated as part of a ca pacitor discharge circuit. With heating rates between 10(8) and 10(9) K/s, temperatures up to about 12000 K can be achieved. The measurement s allow the determination of heat capacity and the mutual dependencies between enthalpy, electrical resistivity, temperature and volume. The y are performed from room temperature up to superheated liquid states far above the normal boiling point. A summary of data of the following elements is given: W, Re, Ta, Mo, Nb, Fe, Co, Ni, Cu, Pb, and In.
