CALPHAD Description of the Super-cooled Liquid from the Mo-Nb-B System with the 2-State Model

In the present work, we assessed with the CALPHAD method via Thermo-Calc the super-cooled liquid (SCL) that leads to the formation of metallic vitreous materials. This research aimed to improve the database for thermodynamic calculations of SCLs in the computational study of materials, specifically some subsystems of the Fe-Mo-Cr-Nb-B system, since its application as a metallic glass coating combines exceptionally hardness, corrosion resistance and wear resistance. Thus, continuing the work of our group that assessed the Fe-Nb-B system with the same methods and models, we described the liquid Mo with the two-state phenomenological model as well as the binary liquids Mo-Nb and Mo-B.
