摘要：
The relations between composition, electronic structure, chemical bond and property of composites of Ti3AlC2/TiB2, Ti2AlC/TiB2 and related single phases of Ti3AlC2, Ti(2)AlCas well as TiB2 are studied by the first principle methods. There are strong ionic and covalent interactions among the interfaces of the composites. These interactions among the interfaces, including whole ionic and covalent bonds of Ti3AlC2/TiB2 are stronger than those of Ti2AlC/TiB2. The results are consistent with the experiment, that the mechanical properties of Ti3AlC2/TiB2 are better than that of Ti2AlC/TiB2.
