Nitriding of nanocrystalline pure Fe induced by surface mechanical attrition treatment

MATEC Web of Conferences, 2015
Properties of nanocrystalline (nc) materials are different from, and often superior to those of conventional coarse-grained counterparts. Unfortunately, it is still difficult to obtain “ideal” (e.g. full-density, residual stress-free, flaw-free, porosity-
