“…[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. The thickness of such films was about 2.5 µm and a grain size of about 50 nm.…”

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.

“…The sintered cementite compact had a measured relative density of 98 pct. [19] Apparently, the previous results were affected by the starting composition, microstruc-was obtained by extrapolating from the dual-phase structure of ␣-Fe ϩ Fe 3 C. Therefore, the heat release was calculated ture, and subsequent treatments (even the load in the test may exert an influence to the final results). The DSC analysis of the milled powders revealed an exothermic reaction at a temperature of 580 K (Figure 1(a)), Microhardness of the cementite bulk was measured to be as high as 1000 HV.…”

“…For example, Li et al. reported a single‐phase cementite film (2.5 μm in thickness) in a C 2 H 2 atmosphere by PVD, and as C 2 H 2 gas pressures increases, it would come from Fe 5 C 2 to Fe 3 C, which was vital for the synthesis of carbides to accurately control the experimental conditions . This method is for the preparation of a two‐dimensional material, limiting its application.…”

Iron carbides and nitrides have aroused great interest in researchers, due to their excellent magnetic properties, good machinability and the particular catalytic activity. Based on these advantages, iron carbides and nitrides can be applied in various areas such as magnetic materials, biomedical, photo- and electrocatalysis. In contrast to their simple elemental composition, the synthesis of iron carbides and nitrides still has great challenges, particularly at the nanoscale, but it is usually beneficial to improve performance in corresponding applications. In this review, we introduce the investigations about iron carbides and nitrides, concerning their structure, synthesis strategy and various applications from magnetism to the catalysis. Furthermore, the future prospects are also discussed briefly.
