The Zn-rich corner of the Zn–Al–Ti ternary system at 723 K was experimentally determined using equilibrated alloys with the aid of diffusion couple approach. The specimens were investigated by means of optical microscopy, scanning electron microscopy, wave dispersive X-ray spectroscope and X-ray powder diffraction. A true ternary phase T was identified and it is in equilibrium with TiAl 3, TiAl 2, α-Al, liq.Zn, TiZn 16, TiZn 8 and TiZn in the system respectively. The solubility of Ti in liquid zinc is 0.3 at.%. The solubility of Zn in TiAl 3 and TiAl 2 is 4.4 at.% and 3.2 at.% respectively and that of Al in TiZn 16, TiZn 8, TiZn 3 and TiZn is 0.4 at.%, 0.2 at.%, 1.7 at.% and 2.5 at.% respectively.
