摘要：
We consider the elastic effect of clusters and propose a size misfit strengthening model. Our approach is similar to solute strengthening, where the size misfit of clusters is assumed to be the sum of elementary atomic misfits. The proposed model is compared to the coherency strengthening model, and the results indicate that our model is applicable to clusters similar to<1 nm in diameter. The prediction of the model is reasonably consistent with the reported experiments of aluminium alloys. (C) 2014 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
