摘要：
The 450 °C isothermal section of the Al-Co-Zn ternary system was determined experimentally by means of scanning electronic microscopy coupled with wave dispersive x-ray spectroscopy, and x-ray powder diffraction. Nine three-phase regions have been confirmed experimentally. The liquid phase is in equilibrium with all Al-Co compounds except Al3Co. The maximum solubility of Zn in AlCo, Al5Co2, Al9Co2 and Al13Co4 is 8.76, 18.14, 1.24, 8.97 at.%, respectively. The Al solubility in the Co-Zn compounds (γ2, γ1, γ, β1) is very small, no more than 0.14, 0.28, 0.32, and 0.62 at.%, respectively. No true ternary compound was found in the present study.
