Study of Elastic Anisotropy of Compounds RhBiX (X = Hf, Ti and Zr)

The study shows the minimum and maximum values of Young’s modulus, Poisson’s ratio and shear modulus of compounds RhBiHf, RhBiTi and RhBiZr at zero pressure using ELATE software. Anisotropy parameters AG and AU for RhBiTi are slightly greater than the respective values of these parameters for RhBiHf and RhBiZr. The ratios of maximum to minimum values of Young’s modulus (Emax/Emin), linear compressibility (βmax/βmin), shear modulus (Gmax/Gmin) and Poisson’s ratio (νmax/νmin) for RhBiTi are 1.12, 1.00, 1.14 and 1.26, respectively. The investigation shows the spatial dependence of Young’s modulus, linear compressibility, Poisson’s ratio and shear modulus of compound RhBiTi through polar plots.
