| Abstract | Nanocrystalline ferrite formation during ball milling pure Fe (0.004%C) has been studied through morphology observation and microhardness measurements. It was found that layer-like structure consisting of nano ferrite firstly formed at the outer surface area of the powder particle at the early stage of ball milling. The microstructures between nano-ferrite and work-hardened regions are different and the boundaries between them are quite clear under SEM and TEM. The hardness of nano-ferrite region is obviously higher than that of the work-hardened region. Further milling led to the particle refinement and formation of nano-ferrite. It has been suggested that the nano crystalline ferrite formed through a transition from dislocation cell wall created by work hardening during ball milling to grain boundary, which is regarded to contribute to the hardness gap between the work hardened structure and the nanocrystalline ferrite. |
