英文摘要	Al(2)O(3) and Y(2)O(3) were used as surface materials of shell mould to centrifugal-cast Ti46Al1B (atomic fraction, %) valves, the interface reaction between shell and alloy and its mechanism were analyzed by SEM and XRD, and oxygen increment in the castings was measured by gas analysis. The results show that the reaction layer thicknesses of Y(2)O(3) and Al(2)O(3) shells are about 90 and 170 mu m, respectively, indicating Y(2)O(3) shell has better thermodynamic stability and smaller increment of oxygen in casting than Al(2)O(3) shell, which is accordant with thermodynamic calculation. So the Y(2)O(3) mould is fitter for casting Ti46Al1B valves than Al(2)O(3) mould.
