Abstract

Thermodynamic assessments of Co-Ge and Co-Si systems were carried out by the CALPHAD technique. Magnetic and non-magnetic terms were approximated by the Hillert and Jarl description and a sub-regular solution model, respectively. Almost all experimental data were well described by the present set of thermodynamic parameters. The calculated results predict that the magnetically induced two-phase separation occurs in the Co-Ge system.
