Abstract

The use of mechanical alloying (MA) to process high nitrogen nanostructural stainless steel from Fe-18 pct Cr-11 pct Mn powder mixtures was analyzed. The relatively high nitrogen concentration in solid solution was attributed to preferential accomodation at dislocation elastic stress fields as well as at nanograin boundaries. It was observed that MA in the attritor produced a maximum of 29.4 pct austenite after 72 hours of milling time. The results show that the resultant grain structure obtained from the MA proesses is nanometric with grain sizes well below 10 nm.
