Popis:	Phase equilibria in ternary Al-Ni-Zr system have been studied using X-ray phase and electron probe microanalyses at 1123 K in the content range of 0–45 at % Al. A fragment of the isothermal section of this system has been plotted. The existence of three-phase equilibria Zr7Ni10 + Zr8Ni21 + Zr2Ni7, τ2-ZrNi2Al + NiAl + Zr2Ni7, NiAl + Ni3Al + Zr2Ni7, Zr7Ni10 + Zr2Ni7 + τ2-ZrNi2Al at 1123 K has been established for the first time. Phase based of binary compound Zr2Ni7 dissolves up to 13 at % aluminum. The crystalline structure of the τ7-Zr5Ni4Al phase has been determined, including structure type U3Si2, spatial group P4/mbm (a = 7.1852(7) A, c = 3.3019(5) A).
