Abstract

The segregation inhibited grain coarsening in nanocrystalline binary alloys was investigated. It was shown that in the general statistical (atomistic) treatment, the segregation inhibited grain coarsening in binary nanocrystalline alloys can be described by analytical expressions, if the effect can ne attained with highly saturated grain boundaries. Relative simple relations, describing the temperature dependence of the stabilized grain-boundary fraction, were described. It was found that below a certain surface/grain-boundary fraction, the minimum was possible only with low surface coverage.
