摘要：

The comment (Joubert, 2022) regarding the controversial "NiW" phase detected in our previous study (Tang et al., 2022) was clarified in this work. Our previous conclusion about the presence of the "NiW" phase in the NiV-W ternary phase diagram is drawn without considering the contamination of C. In this work, alloys with a composition of Ni49V1W50 (at. %) were equilibrated at 1100 and 900 degrees C and characterized. The result showed that the NiW phase observed in the previous work (Tang et al., 2022) was actually Ni6W6C carbide, which resulted in misinterpretation of ternary phase constitutions in our previous studies about Ni-V-W (Tang et al., 2022) and Mo-Ni-W (Tang et al., 2020) systems. A new thermodynamic modeling of the Mo-Ni-W ternary system is performed by excluding the presence of "NiW" phase, and this set of parameters can describe the experimental results reasonably.
