摘要：

The grain size dependence of the strength of nanocrystals is investigated. The inverse Hall-Petch relation which states that the yield strength increases monotonically with decreasing the average grain size is analyzed. A modeling technique based on atomistic simulation of the nanocrystals is presented.
