文摘

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 TiAl₃, TiAl₂, α-Al, liq.Zn, TiZn₁₆, TiZn₈ and TiZn in the system respectively. The solubility of Ti in liquid zinc is 0.3 at. % . The solubility of Zn in TiAl₃ and TiAl₂ is 4.4 at. % and 3.2 at. % respectively and that of Al in TiZn₁₆, TiZn₈, TiZn₃ and TiZn is 0.4 at. % , 0.2 at. % , 1.7 at. % and 2.5 at. % respectively.
