摘要：

The microstructural characteristics of the Ti3AlC2/Al2O3 interface have been investigated by means of transmission electron microscopy (TEM). The orientation relationships (ORs) between the Ti3AlC2 and the Al2O3 oxide scale are shown to be (0001)Ti3AlC2 parallel to(0001)Al2O3 and [1120]Ti3AlC2 parallel to[1210]Al2O3 (OR-1); (0001)Ti3AlC2 parallel to(0001)Al2O3 and [1120]Ti3AlC2 parallel to(1100)Al2O3 (OR-2). A high-resolution TEM image of the interface is presented and two interfacial models are proposed based on the observed orientation relationships.
