Thermal expansion of liquid Al, Cu, Mo, Ta and W

Abstract
Presents experimental data obtained for the variation of the specific volume of the liquid metals Al, Cu, Mo, Ta and W with applied energy produced by pulsed electric heating of wires of the material. The liquid volume was measured by two methods; the first is based on the fact that the variation of the electrical resistance of the wire with applied energy for free expansion of the liquid differs from that when the volume of the liquid is limited by a surrounding capillary tube, and in the second the volume is measured by using the electrical contact between the expanding wire and fixed probes.
