| Sumario: | The processes of solid phase evolution of nanodispersed palladium powder at low temperatures were studied. It has been established that the process of solid phase transformation, which develops over time, forms a hierarchically structured organization of palladium grains from a structurally loose atomic cluster to a micrograin—an encapsulated aggregate of hollow subgrains. The process of grain ordering unfolds at several scale levels. It starts with the inner walls of the hollow subgrains that form the channel structures of the microaggregate and then passes to their surface and the unified encapsulating grain shell. In the collective effects of self-organization, periodic activation of mass transfer is observed, in which nanoparticles of various mesoscale structure organization are involved. |
