Syntheses of Fe1−x C x alloys (forx≲0.15) and carbides (for 0.15≲x≲0.50) can be obtained by room temperature grinding of the elemental Fe and C powders. The formation of cementite is completed after about 20 h, whereas the alloys are synthesized in critical processing conditions. Synthesized cementite has a high density of defects and particle size down to 10 nm.
