| Abstract: | Ti 48 Al 52 foils were examined by high resolution electron microscopy and electron microscopy. It was found that a Ti 2Al phase does exist in the sample tested, which is different from Ti 2AlN or Ti 2AlC phase. There is some further research to be carried out. Firstly, the precise crystal structure of Ti 2Al is to be determined, especially the atom arrangement of the (0001) plane. Secondly, the structure of interface between Ti 2Al and Ti 3Al should be obtained so as to interpret their relation when they grow from the TiAl matrix in more detail. |
