Abstract
The influence of Fe admixture on ordering kinetics in Ni3Al1-xFex was studied by
running Monte Carlo simulations in a model system A3B1-xCx showing similarly to
Ni3Al1-xFex destabilization of the ordered phase when admixing a ternary element C. Detailed
analysis of atomic jump statistics revealed a dominance of the C-atom jumps in the
creation/elimination of antisite defects as well as in the migration of antisites within majority
sublattice. The results elucidate the role of Fe alloying in the kinetics of chemical ordering in
Ni3Al.
