Article Preview

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.
