Abstract
The evolution of a copper precipitate with a diameter of 3·5 nm containing up to 2·0 at.% of vacancies at different temperatures has been studied by molecular dynamics. The diffusion coefficients were calculated for a single vacancy and vacancy concentrations inside the precipitate of 0·5, 1·0 and 2·0 at.%. The diffusion coefficients for each set of vacancies change with time. During the initial stage, the diffusion of populations of vacancies is very close to that of single vacancy diffusi...
