Powders of a nanocrystalline Fe - 1 wt.% C alloy produced by mechanical alloying were consolidated to form a bulk nanocrystalline sample by means of high pressure torsion at 540 o C. The density of the compacts reached 96 % of the theoretical density. The fracture stress of the material was 1 GPa and the microhardness 7.5 GPa, respectively. The grain size was approximately 70 nm and remained...
