摘要	Based on the Monte Carlo simulation conjoined with the embedded atom method (EAM) potentials, the double species model is established to study relaxation of impure Ni3Al grain boundaries. The present double species model suggests that the impure atoms are not only segregating species but also inducing species. The present model also suggests that study of combination of the positive (the impure atoms induce Ni atoms to substitute into Al sites) and the negative (the impure atoms substitute into Ni sites) bulk effects of impure atoms is available, in order to understand dependence of the cohesion of the impure Ni3Al grain boundary (or the Ni enrichment at the impure Ni3Al grain boundary) on the bulk concentration of impure atoms. The double species model is clarified in comparison between the Ni3Al-B and the Ni3Al-Mg systems. (C) 2004 Elsevier B.V. All rights reserved.
