Abstract	Catastrophic breakaway oxidation of Ti3AlC2 occurs during long-term oxidation at 1100 degrees C in air up to 4000 h. Correspondingly, the oxidation kinetics transforms from cubic law to linear law. The transition time is about 3171 h, and the corresponding critical Al content is about 5.99% lower than the initial content. Afterwards, Ti and C start to be oxidized instead of selective oxidation of Al, and Al2O3 scale loses its protectiveness. Meanwhile, voids generated at the Al2O3/Ti3AlC2 interface reduce the oxide scale adhesion. After 3250 h oxidation, Ti3AlC2 still maintains its crystal structure, indicating the capability of bearing great Al lack. (C) 2015 Elsevier Ltd. All rights reserved.
