Microstructural and Compositional Analysis of the Ni–Cr–Mo–Nb–Ta Superalloy with High Stability at High Temperatures

This article analyzes in detail the structural, thermal and mechanical properties of the Ni₅₄Cr₂₈Mo₈Nb₅Ta₅ alloy, as well identify potential applications in areas where exceptional high-temperature performance is required — such as gas turbines, nuclear reactors or aeronautical engine components. Obtaining a very good correlation between the experimental and fitted profiles, as well as the low values ​​of the error parameters (R-factors), confirms the accuracy of the structural model and the validity of the phases identified following the XRD analysis.
