“…For example, the hardness and isotropic (polycrystalline) elastic moduli of cementite have been reported by several authors. [17][18][19][20][22][23][24][25][26][27][28][29] Inoue et al 30,31 reported deformation and fracture behavior of cementite. Umemoto and co-workers 24,28 reported the effect of V, Cr, Mo and Mn on hardness and polycrystalline elastic moduli of Fe 3 C. Single-phase, thin films of cementite have been synthesized by PVD method on a Si substrate, 21,22 and their Young's modulus and Poisson's ratio have been measured.…”

A comprehensive computational study of elastic properties of cementite (Fe3C) and its alloyed counterparts (M3C (M = Al, Co, Cr, Cu, Fe, Hf, Mn, Mo, Nb, Ni, Si, Ta, Ti, V, W, Zr, Cr2FeC and CrFe2C) having the crystal structure of Fe3C is carried out employing electronic density-functional theory (DFT), all-electron PAW pseudopotentials and the generalized gradient approximation for the exchange-correlation energy (GGA). Specifically, as a part of our systematic study of cohesive properties of solids and in the spirit of materials genome, following properties are calculated: (i) single-crystal elastic constants, Cij, of above M3Cs; (ii) anisotropies of bulk, Young’s and shear moduli, and Poisson’s ratio based on calculated Cijs, demonstrating their extreme anisotropies; (iii) isotropic (polycrystalline) elastic moduli (bulk, shear, Young’s moduli and Poisson’s ratio) of M3Cs by homogenization of calculated Cijs; and (iv) acoustic Debye temperature, θD, of M3Cs based on calculated Cijs. We provide a critical appraisal of available data of polycrystalline elastic properties of alloyed cementite. Calculated single crystal properties may be incorporated in anisotropic constitutive models to develop and test microstructure-processing-property-performance links in multi-phase materials where cementite is a constituent phase.

“…In the case of cementite only theoretical (ab initio calculation) tensor of single crystal elastic constants (C ij ) is available [31]. However, the theoretical data (averaged for polycrystalline aggregate) does not agree with experimentally determined Young's modulus (E) and Poison's ratio (m) [32,33]. Finally, using synchrotron radiation during tensile test it was shown that Fe 3 C crystal exhibit almost isotropic elastic properties [6].…”

“…The diffusion data for carbon presented in this work pertain to these directions. 2 For details concerning the dependence of k on the activities a surface and a interface with respect to the operating diffusion mechanism (see [18]). 3 At atmospheric pressure and at the applied treatment temperatures, N 2 does not react with solid iron; it can be regarded as an inert gas.…”

“…This dearth of fundamental knowledge on cementite is mainly due to the difficulty in preparing single-phase (single-or polycrystalline) cementite specimens. In the past, several works dealt with the production of bulk cementite specimens applying different methods [1][2][3][4][5]. Yet, only recently, it was reported for the first time that massive cementite layers can be grown on ferrite substrates by a dedicated gaseous nitrocarburising process [6].…”

Massive, pure cementite layers were grown on ferrite substrates by nitrocarburising in a dedicated NH 3 / H 2 /CO/N 2 containing gas atmosphere at temperatures in the range of 783-843 K. From the parabolic layer-growth constants, an ''apparent'' activation energy for cementitelayer growth of 109 ± 12 kJ/mol was obtained. This ''apparent'' activation energy can be subdivided into a positive contribution due to the activation energy for (tracer) diffusion of carbon in cementite and a negative contribution due to the temperature dependence of the difference of the carbon activity in cementite at the surface and at the interface cementite/ferrite.
