Abstract
Wire-shaped alloy samples are resistively volume heated as part of a fast capacitor discharge circuit. Time resolved measurements with submicrosecond resolution allow the calculation of specific heat and the mutual dependences between enthalpy, electrical resistivity, temperature, and density of the alloy in the solid and liquid phase. Thermal conductivity is estimated from resistivity data by the Wiedemann-Franz law at the end of the solid phase and at the beginning of the liquid phase. These high-speed measurements are compared to results of quasistatic measurements of specific heat obtained by differential scanning calorimetry and expansion measurements by dilatometry. The results are presented and compared with results of other research groups.
