Abstract

Nanocrystalline material was synthesized by ball milling Fe-2C powder in an argon environment attritor which resulted in micron-size powder particles with a substructure (grains) or approx.20 nm. TEM analysis was performed on dynamically-consolidated material after 1 hour heat treatments up to 700°C. Results showed the grain size was essentially unchanged during consolidation and the nanograins were stable up to approximately 550°C, but after 1 hour at 700°C the grains had grown over an order of magnitude to approximately 1000 nm. The grain size stability up to 550°C has real significance because qualitative compression tests revealed a low flow stress with very ductile behavior at 500°C indicating the possibility of secondary forming without loss of nanostructure.
