Abstract: The present study aims to comprehend the thermodynamics of the Al-Ni-Cr superalloy system utilizing the latest Thermocalc 2022b databases. Thermocalc is a software that has a large database which has become vast over the years. The thermodynamic behavior and stability of the system were examined under varying conditions, including temperature and composition. The findings of this study provide crucial insight into the phase behavior and stability of the Al-Ni-Cr superalloy system, which can inform the optimization of its properties and performance for various industrial applications, compared to previous studies and research. The results of this study contribute to a deeper understanding of the thermodynamics of superalloy systems and can be of great benefit to the materials science and engineering communities. The databases used for the binary systems were NIDEMO v2.0 (Nickel Demo database v2.0, including Ni, Cr, and Al – a subset of TCNI) and TCBIN V1.1 (TC Binary Solutions Database, Version 1.0), while for the ternary systems, NIDEMO V2.0 and PURE 5SGTE V5.1 (Pure Elements – Unary Database, Scientific Group Thermodata Europe) were used. The results here demonstrate the great benefits of studying the thermodynamics of this alloy through available database systems and comparing the results with experimental studies.
