The paper presents theoretical temperature dependent mechanical and thermophysical properties of lutetium monochalcogenides using ultrasonic analysis. The higher order elastic constants are evaluated using Coulomb and Born-Mayer potential upto second nearest neighbour. The second order elastic constants are used to compute mechanical parameters such as bulk modulus, shear modulus, tetragonal modulus, Poisson's ratio, Zener anisotropy factor and fracture to toughness ratio for finding future performance of the chosen materials at room temperature. The second order elastic constants are further applied to find out the ultrasonic velocities <100>, <110> and <111> crystallographic directions in the temperature range 100-300 K. Finally Debye temperature, ultrasonic Gruneisen parameters and first order pressure derivatives of lutetium monochalcogenides are computed using the second and third order elastic constants. The obtained results are discussed in correlation with available results on these properties for the chosen materials.

Abstract


The paper presents theoretical temperature dependent mechanical and thermophysical properties of lutetium monochalcogenides using ultrasonic analysis. The higher order elastic constants are evaluated using Coulomb and Born-Mayer potential upto second nearest neighbour. The second order elastic constants are used to compute mechanical parameters such as bulk modulus, shear modulus, tetragonal modulus, Poisson's ratio, Zener anisotropy factor and fracture to toughness ratio for finding future performance of the chosen materials at room temperature. The second order elastic constants are further applied to find out the ultrasonic velocities <100>, <110> and <111> crystallographic directions in the temperature range 100-300 K. Finally Debye temperature, ultrasonic Gruneisen parameters and first order pressure derivatives of lutetium monochalcogenides are computed using the second and third order elastic constants. The obtained results are discussed in correlation with available results on these properties for the chosen materials.
