摘要：
The evolution kinetics of nanopores located at triple junctions has been analyzed during low-temperature annealing of submicrocrystalline materials obtained by intensive plastic deformation. The influence of elastic stresses due to strain-induced disclinations at the junctions and of grain boundary nonequilibrium on nanopore kinetics has been studied.
