The system Fe-Ni-Cr: revision of the thermodynamic description

The phase diagram of the ternary Fe-Ni-Cr alloys has been reassessed for temperatures higher than 1070 K using substantially more thermodynamic data from experimental investigations than previous attempts. The new thermodynamic description reduces the magnetic contribution terms to the expressions of the pure species only. The calculated phase equilibria yield a distinct improved overall-agreement with the experimental data than the results of previous assessments. The present thermodynamic description reproduces the distribution coefficients better than previous data. Complete lists of the data sets of all binary and ternary parameters, several isothermal and vertical sections as well as various projections are presented
