Abstract

âº We present a possible way to bridge CALPHAD and ab initio calculations. âº Thermodynamic modeling of the Fe-Cr system is performed down to 0 K. âº A sign change of magnetic ordering energy of mixing rather than enthalpy of mixing is found in bcc alloys at 0 K. âº Phase separation in the Fe-Cr alloys is studied by atom probe tomography. âº Reasonable chemical spinodal curve of the Fe-Cr system is predicted.
