中文摘要	The effect of 10 at.%Cr on the oxidation resistance of TiAl intermetallic compound at 800-1100 degrees C in air was investigated The results indicated that 10 at.%Cr equally substituting for Ti and Al in TiAl alloy had duplex effects on the isothermal kinetics of TiAl. At lower temperatures (800-900 degrees C), Cr increased the oxidation rates as a result of the doping effect of Cr in the scale and at higher temperatures (1000-1100 degrees C), especially at 1100 degrees C, Cr significantly reduced the oxidation rates as a result of the formation of a continuous Al2O3 film on the surface. 10 at.%Cr only substituting for Ti in TiAl alloy remarkably reduced the oxidation rates at all temperatures by about two orders of magnitude. Moreover, 10 at%Cr significantly improved the cyclic-oxidation rsistance of TiAl alloy.
