Abstract

The Cr-Pt system has been reassessed with the CALPHAD method based on experimental data and first-principles calculations. First-principles calculations have been performed on the ordered structures and special quasirandom structures have been used on the fcc disordered phase to compensate for scarce experimental data. A four sublattice model has been chosen to describe the ordering reactions between the high temperature fcc phase and the low temperature L1 2 and L1 0 phases. X-ray diffraction and calorimetric measurements have been performed to provide information about the transformation of phases.
