The phase composition and structure of nickel alloy VZh172 with elevated content of niobium and zirconium in cast and deformed conditions and after a heat treatment and long-term heating at the operating temperature are studied. The role of the alloying elements in formation of the phase composition is determined. The content, chemical composition, crystal structure of the intermetallic phases, the morphology of their particles, and the effect of the phase composition on the mechanical properties of the alloy are considered.
