“…The temperature dependence of Young's modulus is similar to what is obtained for paramagnetic materials where no phase transformation occurs over the investigated temperature range [32]. This behavior has been observed in several materials such as pure metals [32,33], steels [34,35], intermetallics [36,37], quasicrystals [38,39] and superalloys [40,41].…”

Temperature dependencies of the elastic moduli and thermal expansion coefficient of an equiatomic, single-phase CoCrFeMnNi high-entropy alloy, Journal of Alloys and Compounds (2014), doi: http://dx. AbstractThe equiatomic CoCrFeMnNi alloy is now regarded as a model face-centered cubic singlephase high-entropy alloy. Therefore, determination of its intrinsic properties such as the temperature dependencies of elastic moduli and thermal expansion coefficient are important to improve understanding of this new class of material. These temperature dependencies were measured over a large temperature range (200 -1270 K) in this study.

“…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.
