K. B. Kalmykov, N. E. Dmitrieva, S. F. Dunaev, D. M. Kondratiev Phase equilibria in the Al–Ni–Cu–Zr system At 1123 K and more than 30 atomic percent of zirconium Abstract By using of the X-ray analysis, the X-ray microanalysis, the scanning electron microscopy and the differential scanning calorimetry the phase equilibria in the quaternary Al–Ni–Cu–Zr system at 1123 K and zirconium concentrations more than 30 at.% were determined. The area of existence of the four-component liquid phase with melting point 1110 K, at concentrations of copper and zirconium 15.1 and 58.0 at.% respectively was detected in the system. The content of other components vary in 13,4–19,5 Al and 7,4–13,5 at.% Ni. Firstly the existence of seven four phase equilibria was determined experimentally.Key words: phase equilibria , X-ray microanalysis , X-ray analysis , bulk amorphous materials.
