Shaner, J W; Gathers, G R; Minichino, C

An apparatus was developed to make simultaneous measurements of enthalpy, temperature, volume, and electrical resistivity on metals in the temperature range from 2500 to 8000/sup 0/K and at pressures up to 1 GPa. Cylindrical samples are resistively heated by a 10-50 ..mu..s current pulse in a constant pressure inert gas environment. Data for the refractory transition metals Nb, Mo, Ta, and W are presented.
