“…The interfacial reaction degree of alumina shell mould with Zr sol as binder is less than SiO 2 binder [41]. Besides, composition design of TiAl alloy (for example, adding TiB 2 ) can effectively reduce the interfacial reaction degree [42]. Therefore, reducing or not using SiO 2 as binder and optimising the composition of TiAl alloys can alleviate the interfacial reaction.…”

Intermetallic TiAl alloys are new generation high-temperature material. However, extensive application of TiAl alloys is hindered by some disadvantages, especially the high processing cost. Currently, precision casting is an effective method to manufacture TiAl components with complex shape. However, the interfacial reaction between the TiAl alloy melt and mould affects the quality of the castings and hinders extensive applications of casting TiAl components. In this paper, the research status of mould materials for the casting of TiAl alloys is reviewed. Performances of present used mould materials are compared in details. Reaction mechanisms between mould materials and the melts of TiAl alloys are also summarised. Finally, the future development tendency and prospect are pointed out.
