Sound speed and thermophysical properties of liquid iron and nickel

Abstract

An electrical-pulse-heating technique has been used to heat iron and nickel to high temperatures to measure thermophysical properties in the liquid state. A dynamic technique was used because static techniques, which are capable of greater precision, fail at a relatively low temperature. Measurements have been made, and results are shown for enthalpy, temperature, density, electrical resistivity, and sound speed up to 3950 K in iron and 4250 K in nickel.
