| 中文摘要 | An alloy of the nominal composition of Ti-62.5at.% Al was annealed at 1000 degrees C. Transmission electron microscopy (TEM) was performed to study the microstructure. Two types of crystallographic orientation relationships (ORs) between Ti3Al5 and TiAl2L (L for long period) were found. They respectively correspond to different phase interfaces. Most of the observed interfaces correspond to an OR of aTi(3)Al(5) // aTiAl(2)(L), cTi(3)Al(5) // cTiAl(2)(L). Such a type of (001) interfaces contains dislocation networks with orthogonal Burgers vectors along [110] and [110]. (101) interfaces containing ledges can occasionally be observed. The corresponding OR slightly deviates from bTi(3)Al(5) // bTiAl(2)(L), aTi(3)Al(5) // cTiAl(2)(L). The different interfaces are accounted for misfit between Ti3Al5 and TiAl2L, and might result from different phase transition procedures. |
