Descrição termodinâmica via CALPHAD do líquido super-resfriado no Sistema Mo-Nb-B com o modelo de 2-Estados

Abstract

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.
