| Abstract: | It is shown experimentally that the formation of submicrocrystalline and nanocrystalline states significantly affects the stability of the high pressure hcp phase in iron-based alloys. It is established that the manganese segregation from the bulk of ɛ-phase grain to the grain boundary under high hydrostatic pressure can influence the stability of this phase in nanocrystalline alloys. |
