Nanostructured Materials, 1997
Nanocomposites Fe-85 vol.% Fe3C were prepared by mechanosynthesis (MS) of elemental Fe and graphite powders. The crystallite size in the MS powder was about 7 nm for Fe3C and about 8 nm for Fe. These powders were densified by a field assisted sintering process.

Atomic structure of the austenite-cementite interface of proeutectoid cementite plates
Philosophical Magazine A, 1999Abstract In a previous investigation, the atomic habit plane (or terrace plane) of proeutectoid cementite plates in austenite was deduced to be (113)A‖(101)c (where the subscript A indicates austenite and the subscript C cementite), based on conventional transmission electron microscopy and computer-aided atom matching studies.

Kinetics of cementite mechanosynthesis
Hyperfine Interactions, 1992The influence of ball to powder ratio and discontinous milling during ball milling of Fe0.75C0.25 elemental powder mixture is presented. The formation of Fe3C cementite, Hagg and e carbides has been follwed by X-ray diffraction and Mossbauer Spectroscopy. Higher ball to powder ratios induce faster kinetics. Synthesized cementite has crystallite sizes 9

Abstract Small angle tilt boundaries consisting of uniformly spaced edge dislocations were observed in cementite extracted from an annealed steel. The Burgers vector of the dislocations was identified as [0b0] from their average spacing and the tilt angle between both grains. The [0b0] type dislocation was related with two displacement vectors required

Corrosion Science, 1974
Abstract The progressive changes in texture which occur during the oxidation of two different preparations of cementite (A and B) have been investigated by electron microscopy. Changes in surface texture observed during the reaction of cementite A with gaseous oxygen were ascribed to the initial formation of a coherent barrier layer of Fe3O4, the ...

The hot hardness was measured on the (010) plane of primary cementite in unidirectionally solidified iron-carbon, iron-carbon-chromium, and iron-carbon-boron alloys at temperatures up to 973 K, using a hot hardness tester equipped with an indenterheating system.
