摘要：
Optical and scanning electron microscopy, electron microprobe analysis, and X-ray diffraction are employed to examine alloys in the Cu–Ti–Zr ternary system, annealed at 750°C, with copper content from 0 to 50 at.%. A partial isothermal section of the phase diagram is constructed at 750°C in the composition range in question. The existence of a continuous series of solid solutions between CuTi2 and CuZr2 isostructural compounds (γ phase, MoSi2 type) is confirmed. The homogeneity ranges of Cu2TiZr ternary compound (τ1, MgZn2 type) and β-(Ti, Zr), (CuTi) (CuTi type), and CuZr (CsCl type) solid solutions are determined.
