摘 要:<正> A thermodynamic analysis of the ultrafine crystallites in nanocrystalline materials was presented inthis work.It was deduced that the structure of the nm-sized crystalline grains is different from theperfect crystal lattice,characterized by two possible structure changes;supersaturation of alloy ele-ments and crystal lattice distortion resulted from supersaturation of vacancies.Some experimental ev-idences in the literature,which are in agreement of the thermodynamic consideration,indicate thatthe structure changes in the nm-sized crystallite seems to be a consequential feature of thenanocrystalline materials.
