Influence of processing conditions on in situ generation of nanocrystalline Fe(3)AlCx and Fe-Al phases during mechanically activated annealing and sintering of Fe-40 at% Al alloy was evaluated. Fe(3)AlCx, Fe3Al and ordered FeAl phases evolved even at a low temperature of 400 degrees C. The presence of carbide phase was attributed to the free carbon originating from the organic process control agent while its formation at low temperature was correlated to fast diffusion of C in the lattice assisted by the nanocrystalline structure coupled with the presence of thermal vacancies in the Fe-40 at% Al alloy. The as-sintered composite showed improved mechanical properties.
