| Abstract | Structural stability of nanograined (NG) metals at elevated temperatures or under mechanical loadings is much reduced relative to that of their coarse-grained counterparts, bottlenecking their processing and applications. In this paper, we present recent progress in stabilization of NG metals with grain boundary (GB) relaxation mediated by interactions of GBs and partial dislocations. Two strategies for inducing GB relaxation were identified in NG and submicro-grained pure metals: plastic deformation of nanograins below critical sizes and rapid heating for forming annealing twins. With the GB relaxation, both thermal stability and mechanical stability of nanograins in several pure metals are enhanced significantly. (C) 2020 Acta Materialia Inc. Published by Elsevier Ltd.
