摘要：

The 600 and 800 degrees C isothermal sections of the Al-Cr-Sn ternary system were determined based on examination of equilibrated alloys by X-ray diffraction and scanning electron microscopy coupled with energy dispersive spectroscopy. The experimental results indicate that seven and four three-phase regions exist in the Al-Cr-Sn system at 600 degrees C and 800 degrees C, respectively. The Al11Cr2 phase is found in both two isothermal sections. The Al11Cr4 Phase is confirmed, and is stable in the 600 degrees C isothermal section; its decomposition temperature is between 690 degrees C and 800 degrees C. The solubility of Sn in Al-Cr binary compounds is negligible. Six intermediate phases, i.e., Al7Cr, Al11Cr2, Al4Cr, Al11Cr4, Al8Cr5 and AlCr2, and no ternary compounds are found in this work.
