The isothermal section at 370°C of the Zn–Al–Ti ternary system in the Zn-rich region was investigated experimentally using scanning electron microscopy coupled with energy dispersive X-ray spectroscopy and X-ray diffraction. The experimental results reveal that T + TiZn 16 + TiZn 8 , T + TiZn 16 + η-Zn, T + TiZn + TiZn 8 , TiZn + TiZn 3 + TiZn 8 , T + η-Zn + (α-Al), T + (α-Al) + TiAl 3 and T + TiAl 3 + TiAl 2 are the seven three-phase equilibria in the Zn–Al–Ti system. T phase is a true ternary phase and it is in equilibrium with TiAl 3 , α-Al, η-Zn, TiZn, TiZn 8 and TiZn 16 at 370°C, respectively. The content of Zn in T phase varies from 12.8 to 56.8 at.%, Al varies from 17.7 to 59.5 at.% and Ti varies from 24.2 to 27.8 at.%. Ti 2 Al 5 was not found in the Zn–Al–Ti system at 370°C.
