Abstract

A partial phase diagram for the system Cu0.5Au0.5-xNix with x ≤ 0.15 was determined by electrical resistivity measurements and X-ray powder diffraction. Substitution of only 2.8 at.% Ni for gold in equiatomic CuAu eliminated the CuAuII long-period superstructure from the phase equilibria. The presence of a two-phase coexistent region separating the CuAuI-type ordered phase and the disordered solid solution was evidenced. The solvus curve was determined by the parametric method and the solubility limits of nickel for the CuAuI-type superstructure at 300 and 320 °C were found to be 7.0 and 8.0 at.% Ni respectively.
