Abstract

Abstract

The formation energy of all possible ordering structures formed by different Nb occupation in Ti sublattice of TiAl with various composition is calculated using the pair-wise potential model. The Nb occupation way with minimum energy is found. The rules of Nb occupation with different Al content were obtained.
