Yong Liang, Shuangjie Wei, Maoxing Ling, Ya Liu, Mingjun Pang, Yongzhong Zhan and Wenbiao Zhou


The phase equilibria of the Al-Cr-Pr ternary system at 773 K have been experimentally determined based on results of X-ray diffraction, scanning electron microscopy and energy-dispersive X-ray analysis. 2 ternary compounds, Al20Cr2Pr and Al8Cr4Pr, as well as 11 binary compounds, i. e. Al7Cr, Al4Cr, α-Al9Cr4, α-Al8Cr5, AlCr2, α-Al11Pr3, Al3Pr, Al2Pr, α-AlPr, AlPr2 and β-AlPr3 were confirmed. No compound was found in the Pr-Cr binary system. The isothermal section of the Al-Cr-Pr ternary system at 773 K consists of 15 three-phase regions, 30 two-phase regions and 16 single-phase regions. Homogeneity ranges of intermetallic compounds at 773 K have been determined.
