[en] The isothermal sections of the Ag-Cr-Zr ternary system at 1000 and 750 C were experimentally established. A series of phases as well as their compositions and crystal structures were characterized on the annealed alloys by means of optical microscopy, electron probe microanalysis, scanning electron microscopy and X-ray diffraction. Our studies have detected four three-phase regions at both 1000 and 750 C. (Ag) was observed to exist in the solid state at 750 C, and in the liquid state at 1000 C. No ternary compound was found in this system. The maximal solubilities of Cr in (Ag), Ag in ZrCr₂, and Cr in AgZr₂ at 1000 C are 4.12, 2.13, 0.91 at.%, respectively. At 750 C, the solid solubilities of Cr in AgZr, AgZr₂, and that of Ag in αZrCr₂ are determined to be about 1 at.%.
