The partial isothermal section at 800°C is represented for the first time. The structure of the Al–Cu–Ir alloys in the Al70Ir30–Al40Cu60–Al range, which are quenched from 800°C, is investigated by SEM/EDX and XRD methods. Three ternary phases (decagonal quasicrystalline D1, orthorhombic ε6, and cubic (fcc) C2) are stable at this temperature. The (Al9Ir2), φ, ε6, D1, γ1, and є2 phases coexist with a liquid phase at 800°C.
