that the high temperature oxidation resistance of TiAl-based alloy was greatly improved by forming such composite coating. No spallation and crack happened and the weight gain was very small after cycle oxidation at 900℃ for 314h.

Interface structure and shear strength of brazed joints of TiAl-based alloy to middle-carbon steelFENG Ji-cai(冯吉才), LIU Hui-jie(刘会杰)(State Key Laboratory of Advanced Welding Production Technology, Harbin Institute of Technology, Harbin 150001, China)Abstract:Vacuum brazing of a TiAl-based alloy to a middle-carbon steel was carried out at 1173K for 0.5-40min with a Ag-Cu filler metal......
be evidenced that TiAl-based composite reinforced with 10% Nb was much more ductile than conventional TiAl [16]. The excellent ductility of TiAl-based composite with high-content Nb could be attributed... compression test are shown in Fig. 7. Brittle fracture for TiAl-based composite was exhibited because of no trace of plastic deformation and a combination of trans- and inter-crystalline crack growth. 4......
