摘要：
High temperature drop calorimetry measurements of enthalpy increment have been made on phase pure UFe2 compound for temperatures up to 1,473 K. The measured data agreed well with the earlier reported data that are available only up to 1,000 K. An integrated modelling of the present heat capacity data has been made using the framework of quasi-harmonic Debye-Grüneisen formalism, the input parameters for which have been obtained after a critical appraisal of the available thermophysical data. The modelling yielded fully consistent estimates of both heat capacity and volume thermal expansivity, for the complete temperature range, 0–1,273 K.
