Abstract
The phase equilibria at 340°C of the Al – Ni – Zn system were investigated by combining the diffusion couple technique with the equilibrated alloys method. The samples were examined by means of optical microscopy, X-ray diffraction, scanning electron microscopy, and electron probe microanalysis. Two ternary compounds (1 and 2) were found to exist at 340°C. The solubilities of Zn in AlNi, Al3Ni2 and Al3Ni were determined to be about 20, 2 and 1 at.% Zn, respectively. The solubilities of Al in β1-NiZn and in were measured to be about 11.5 and 1 at.% Al, respectively. The solubilities of Zn in both AlNi3 and Al3Ni5 are below 1 at.% Zn.
