THERMOPHYSICAL PROPERTIES OF SOLID AND LIQUID TUNGSTEN

The thermophysical properties of solid and liquid tungsten have been measured up to an enthalpy of H = 1.4 MJ · kg-1 using an isobaric expansion technique. These measurements give the pressure, temperature, volume, enthalpy, electrical resistivity, and sound velocity as fundamental quantities. From these, other properties may be calculated, such as specific heat at constant volume and pressure, heat of fusion, isothermal and adiabatic bulk moduli and compressibilities, and thermodynamic γ. Results of these calculations are presented for liquid tungsten and compared with literature values where such data exist. These data will help in understanding liquid-metal phenomenology theoretically and in the design and modeling of exploding wires, foils, and fuses. © 1990 Plenum Publishing Corporation.
