The 600 and 800 °C isothermal sections of the Al-Ni-Sn ternary system were determined based on examination of equilibrated alloys by SEM spectroscopy and x-ray powder diffraction. Nine and Six three-phase regions exist in the Al-Ni-Sn system at 600 and 800 °C respectively. All the Al-Ni and Sn-Ni binary compounds except Al 3 Ni 4 were confirmed at 600 °C, no ternary compound exists in Al-Ni-Sn system. The Ni 3 Sn 2 , Ni 3 Sn and AlNi 3 phases show a large solubility of the third element. No ternary compound exists in Al-Ni-Sn system.
