The oxidation behavior of TiAl-Cr（mole fraction of Cr：0-20%） was investigated at 1 173 K in air. The microstructure and composition of the oxide scale were studied by X-ray diffractometry（XRD）, scanning electron microscopy（SEM） and electro-probe micro-analyses（EPMA）. The results show that with the a...
