“…The temperature dependencies could be extrapolated down to a temperature of about 500 K. Despite the different heating rates, both methods used here give very good agreement of the obtained thermophysical data within the stated uncertainties of each experiment. The fast pulse-heating technique can suppress phase transformations in the solid phase [34] and allows measurements in metastable phases. Therefore, one has to be very careful in data evaluation, and all data have to be compared with quasi-static methods.…”

Measurements of the enthalpy, electrical resistivity, and specific heat capacity as a function of temperature starting from the solid state up into the liquid phase for Fe, Ni, and Pt are presented. Two different measurement approaches have been used within this work: an ohmic pulse-heating technique, which allows -among others -the measurement of enthalpy, specific heat capacity, and electrical resistivity up to the end of the stable liquid phase, and a differential-scanning-calorimetry technique (DSC) which enables determination of specific heat capacity from near room temperature up to 1500 K. The microsecond ohmic pulse-heating technique uses heating rates up to 10 8 K·s −1 and thus is a dynamic measurement, whereas the differential-scanning-calorimetry technique uses heating rates of typically 20 K·min −1 and can be considered as a quasi-static process. Despite the different heating rates both methods give good agreement of the thermophysical data within the stated uncertainties of each experiment. Results on the metals Fe, Ni, and Pt are reported. The enthalpy and resistivity data are presented as a function of temperature and compared to literature values.

“…Although some references to specific heat evaluations were listed in this review, measurements of Hausch [64] and references therein were not mentioned. Later Seifter et al [65] measured the enthalpy and some physical properties of FeeNi alloys in a temperature range from room temperature to 2400 K.…”
