dc.description.abstract© 2022, Pleiades Publishing, Ltd.Abstract—: Zr–Nb–N nitride ceramics have been prepared via nitridation of rolled Zr–Nb solid solutions at temperatures of 1700, 1900, and 2400°C. We have determined the phase composition of the as-rolled alloys and the composition of the heterostructures and compact nitride obtained. Interaction of solid solutions of niobium in zirconium (0.1–10 wt % Nb) with nitrogen at temperatures below and above the peritectic reaction temperature has been shown to occur in two steps. In the first step, the solid solution decomposes to give zirconium nitride and metallic niobium embedded in its bulk: Zr〈Nb〉 + N2 → ZrN1 –х + β-Nb. In the second step, the metallic niobium reacts with nitrogen: ZrN1 –х/β-Nb + N2 → (Zr,Nb)N. The resulting niobium nitride dissolves in the ZrN, reducing the lattice parameter of the zirconium nitride.
