This work presents an experimental study of the ter nary Co–Ni–Zr system in the ZrCo–ZrNi–Zr2Ni–Zr 2Co composition region by means of optical microscopy, X-ray diffraction and differential thermal analysis . The study shows that the ZrCo–ZrNi section is pseudobin ary and has a peritectic character. Including the phase equilibria in the binary systems, the partial ternary system may be characterized by the following inv ariant equilibria, Р: L + ZrCo ↔ ZrNi, Е: L ↔ ZrCo + Zr 2Co, U: ZrCo +L ↔ Zr 2Co1-xNiх + ZrNi, Е: L ↔ ZrNi + Zr 2Ni. The Zr57Co43–Zr 57Ni43 section has been constructed.
