... 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. ...
