Abstract：Combined with optical microscope (OM), X-ray diffraction (XRD) and electron probe microanalysis (EPMA), phase equilibria of the Al-Ce-Ge system at 500 ℃ was investigated by equilibrated alloys method. The results show that, five ternary compounds, i.e. α(CeAl1.62Ge0.38), β(CeAl2Ge2), γ(CeAlGe), δ(CeAlGe2) and ε(Ce2AlGe6) as well as the liquid phase are verified at 500oC and the homogeneity range of the δ phase is Ce24.7~24.8Al33~33.9Ge41.3~42.3. Two new ternary compounds, i.e. η(Ce61.3Al21.9Ge16.8) and μ(Ce55.9Al11.1Ge33), are observed. In addition, seven three-phase regions α+CeAl3+γ, Ce3Al11+CeAl3+γ, αCeGe2-x+CeGe+γ, CeAl+CeAl2+Ce5Ge3, Ce3Ge+Ce5Ge3+Ce3Al, CeAl+Ce3Al+η and CeAl2+Ce5Ge3+μ are observed.
