Resumen
In the present work, we will use the Thermo-CalcTM software to model
with the CALPHAD method the super-cooled liquid (SCL) that leads to the
formation of metallic vitreous materials. This research aims 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 modeled the Fe-Nb-B system with the same methods and
models, we will describe the liquid molybdenum through the 2-state
phenomenological model as well as the binary liquids Mo-Nb and Mo-B.
