Response to the comment by Holm, Foiles, Homer and Olmsted on 'Towards realistic molecular dynamics simulations of grain boundary mobility' by Zhou and Mohles

摘要

In the present issue of Scripta Materialia, Holm et al. comment on a paper previously published by the present authors (J. Zhou, and V. Mohles, Acta Materialia 59, 5997 (2011)), in which we presented molecular dynamics (MD) simulations of grain boundary (GB) motion with a new method to derive GB mobility. The GB mobilities derived from these simulations contradicted previous MD simulations, but were in reasonable agreement with our experimental findings. In their comment, Holm et al. aim to disprove our new method. However, they utilize a simplistic model and use misinterpreted data from our paper for their alleged proof and conclusions. The present paper points out where Holm et al. err.
