Description

Interaction between coherent Ag particles and Cu grain boundaries (GBs) has been investigated by molecular dynamics simulations. Through measuring GB energy evolution as a function of GB position during the interaction, the maximum pinning force was directly determined and found to agree well with theoretical predictions. The relationship between the maximum pinning force and the pinning efficiency for different GBs has been discussed. It is concluded that the two parameters are irrelative to each other, as also observed in experiments.
