Abstract:When exposed to moderate to high temperatures, nanomaterials typically suffer from severe grain coarsening, which has long been a major concern that prevents their wider applications. Here, we proposed an effective strategy to inhibit grain coarsening by constructing grain boundary (GB) complexions with multiple dopants co-segregated, which hindered coarsening from both energetic and kinetic perspectives. As a demonstration of the feasibility of the strategy, multiple selected dopants were doped to a ZrO2-SiO2… Show more
