Abstract
Physicochemical analysis methods (metallography, X-ray diffraction, differential thermal analysis, and electron microprobe analysis) are used to first study the ZrCo–ZrNi alloys in the temperature range that includes their melting and crystallization. The phase diagram of the system is constructed. The phases based on ZrCo (crystal structure of CsCl type, maximum nickel solubility about 46 at.%) and ZrNi (crystal structure of CrB type, cobalt solubility about 2 at.%) coexist in a range from room to subsolidus temperatures. The phase diagram is of peritectic type with peritectic point coordinates 1240 ± 12°C and ~48 at.% Ni.
