A homemade Ca(Y)-doped BaZrO3 crucible was used to melt TiAl alloys. The microstructure of the melt TiAl alloy and the interficial reaction between the Ca(Y)-doped BaZrO3 crucible and TiAl melt were analyzed by optical microscopy, scanning electron microscopy, X-ray diffraction and atomic emission spectrometry, respectively. The results demonstrate that the microstructure of TiAl alloys is largely composed of lamellar α2+γ with different orientations and small amount of bulk γ phase, the melts exhibit poor wettability on Ca(Y)-doped BaZrO3 crucible and no reaction layer is observed between them. No obvious element diffusion is observed between crucible and metal. This may imply that Ca(Y)-doped BaZrO3 is a promising candidate of materials of TiAl alloys.
