Effects of Nb and Al Contents on the Nb Ordering in TiAl
The energy of different Nb disordering and ordering substitution in TiAl with various composition is calculated using the pair-wise potential model. It is observed that the Nb atoms situated on the Ti sublattice in TiAl, and the increasing of Nb and Al contents is beneficial for the ordering occupation of Nb atoms.
