The lattice thermal conductivity and Young’s modulus of a material are related as: \(K_{L} \sim\sqrt Y\) 69. Pugh’s ratio70,71,72 provides with the information about the brittle/ductile nature of a material. If the value of G/B is higher than 0.57, the material is brittle, ...
Table 2 presents the single-crystal elastic stiffness constants cij and the polycrystalline average elastic modulus (bulk modulus Bave, shear modulus Gave, Young's modulus Eave, Poisson's ratios vave) for α-Mg, β′-Mg7Gd, γ''-Mg2GdAg3, and the α/γ''/α phase. The hexagonal crystal...
Other methods are developed to extract elastic constants from highly textured samples only.14, 15 Nanoidentation modulus measurement coupled with orientation measurement using electron backscatter diffraction (EBSD) have recently been applied to obtain orientation-dependent Young’s modulus, but the ...
22. The Young's modulus E and Poisson's ratio v were obtained from Eq. 23 and Eq. 24, respectively. The universal anisotropy ratio is given by Au in Eq. 2580. An elastically isotropic crystal has an Au value of 0. GV ¼ C11 À C12 5 þ 3C44 ð21Þ GR ¼ 5ðC11 ...

A given crystal structure cannot exist in a stable or metastable phase unless its elastic constants obey certain relationships. They also determine the response of the crystal to external applied forces, as characterized by the bulk modulus, shear modulus, Young’s modulus, and Poisson’s ratio. ...
