| Abstract | Interfacial segregation has been reported to play a critical role in the thermal-mechanical stability of nanocrystalline Mg alloys. Here we report Ag-segregation-assisted formation of nanocrystalline Mg-Ag alloy with high proportion of sub-grain boundaries during conventional rolling. The segregation structure is determined by dislocation configurations and subsequent strain field and misorientation of the subgrain boundary. It indicates that the alloying elements, which induce < c+ a > dislocations, would help to improve the stability of interfaces. (C) 2020 Acta Materialia Inc. Published by Elsevier Ltd.
