International Materials Reviews, 2019 Cementite occurs in steels, in meteorites, possibly at the core of the Earth and has uses in its pure form. It's composition can deviate from , but not by much because the Fe–C bond contributes to its cohesion. Its crystallographic unit cell is orthorhombic and primitive, with large lattice parameters, explaining its hardness.

Thermal, compositional, and compressional demagnetization of cementite
American Mineralogist, 2015 The 1 bar Curie temperature, T C , at which cementite (anthropogenic form of the mineral cohenite, nominally Fe 3 C) abruptly loses ferromagnetism, is found to be sensitive to small deviations from the stoichiometric cementite composition. Stoichiometric Fe 3 C begins to lose magnetic susceptibility at 187 °C.

Metallurgy and Foundry Engineering, 2007 The aim of the studies performed was to assess an influence of crystallographic orientation relationship (OR) between pearlitic ferrite and cementite on a stability of cementite plates. Diffraction analysis made with an electron microscope showed the existence of the Bagaryatski OR and the Pitsch OR both in the pearlite structure after eutectoid ...

Kinetic Modeling of Grain Boundary Cementite Evolution [PDF]
, 2022 Prediction of grain boundary cementite growth kinetics in hypereutectoid steels is necessary to control its thickness. It is a question of major industrial importance but has remained unresolved to date. This paper presents and compares two different and
