Abstract

The fast pulse heating of metallic wires lea a conversion of the solid over the liquid into th ous state of the sample. Under certain conditionE siderable superheating of the liquid can be accon For experiments in water at atmospheric pressure ting rates >10 K/sec we obtain a thermodynamic .9 the sample close to the critical point. By applyi additional static pressure - up to 4 kbar - for c elements we even achieve a critical transition. P ratus and method for the measurement of various t physical data including the critical point of liguid metals is described. Most emphasis is put on the it tion of a multi-wavelengths pyrometer with nsec-resolution.
