Abstract

Nanocrystalline iron synthesized by mechanical alloying and spark plasma sintering exhibited high yield and ultimate compressive strengths of 2.59 and 3.08 GPa, respectively, with a total true strain of 0.05. Partial recrystallization led to a true strain of 0.4 with a lower strength of 2.25 GPa. A bimodal grain size distribution consisting of average fine grains of 2.5 μm and nanograins of 85 nm is attributed to the combined high strength and large plastic strain.
