摘要：
We have employed atomic simulations to compute the resistance to glide posed by two kinds of interfaces: coherent and semicoherent interfaces, and incoherent interfaces. Both kinds offer significant resistance to crossing of glide dislocations but for different reasons. We discuss the implication of the results of the atomistic calculations to the strength of multilayer composites and show that a simple prediction can be made for the upper bound strength of coherent systems.
