“…Later, Yaqoob and Joubert reinvestigated experimentally and reassessed this binary system, and agreed well with most experimental data [6] . Furthermore, the invariant reaction temperature and corresponding compositions determined by Yaqoob and Joubert [6] were reconfirmed by Boettinger et al [55] . Thus, the thermodynamic parameters from Yaqoob and Joubert [6] were directly employed in the present work.…”

Thermodynamic databases are essential prerequisites for developing advanced materials, such as Ni-based superalloys. The present work collects a large amount of experimental and first-principles calculation data concerning the thermodynamics and phase diagrams of the Ni-Mo-Re system, based on which the thermodynamic properties of the ternary and its binary sub-systems Ni-Mo and Mo-Re are assessed by means of the CALculation of PHAse Diagrams (CALPHAD) approach. The thermodynamic database containing all model parameters is established and most experimental data are reproduced satisfactorily. The present work demonstrates the use of the CALPHAD method as a practical appliance in the toolbox of materials informatics to analyze and discriminate various types of data by thermodynamic modeling and then produce more useful data in wider ranges of compositions and temperatures by computational predictions.

“…These discrepancies are not entirely unexpected given that our approach is intended to push the accuracy-speed trade-off in favor of speed. Our methods might provide a lower accuracy for the prediction of phase boundaries (especially the liquid phase) compared with experimental studies [30] but enable the efficient prediction of the stability of novel candidate Fig. 2 SQS's with different concentrations of both sublattice for D0 19 phase.…”

Ab initio high-throughput efforts are continuously identifying new intermetallic compounds in a wide range of alloy systems that were previously thought to be well-characterized. While such predictions are likely valid near absolute zero, they carry the risk that such phases become unstable at the higher temperature relevant to typical synthesis conditions. We illustrate how this possibility can be rapidly tested by integrating Calphad modeling into the high-throughput loop. As an example, we investigate the Ni-Re system, in which D019 and D1a phases were predicted as possible intermetallic compounds. We confirm that these phases are indeed stable at practical synthesis temperatures and explain how they could have been overlooked in prior assessments.
