Impurity atoms have a significant effect on the strength of metals processed by severe plastic deformation (SPD), but their strengthening mechanism is still under argument. To gain an insight into the strengthening mechanism, iron samples with differ

This paper reviews the ductility of nanostructured and ultrafine iron obtained using a variety of methods. Mechanical milling of powder and subsequent hot consolidation, one of the most popular methods offer high mechanical strength but poor ductilit

High dense bulk specimens of 0.55% C steel with ferrite grain sizes in the nanocrystalline and ultrafine regimes have been produced by a warm consolidation process from ball-milled iron powder and subsequent heat treatments. The resulting microstruct

The strain rate sensitivity of three steels with carbon contents ranging from 0.05 to 0.55 wt.% has been determined by nanoindentation and compression tests in the nanocrystalline and ultrafine-grained ranges. Samples were obtained by warm consolidat

The strength and ductility of bulk nanostructured and ultrafine-grained iron containing 0.39% oxygen by weight was determined by tensile tests. Samples were obtained by consolidation of milled iron powder at 500 degrees C. Heat treatments were design
