摘要
The domain orientations and lamellar interfaces play a critical role in the mechanical properties of TiAl based alloys. An umambiguous experimental determination of all six domain orientation in lamellar structure and the interfaces between neighboring gamma laths in a (alpha(2) + gamma) two-phase TiAl alloy containing Mn and Nb were analyzed by means of convergent-beam electron diffraction. The frequency of different interface types are reported. (C) 2002 Acta Materialia Inc. Published by Elsevier Science Ltd. All rights reserved.
