摘要

The theoretical investigation has been performed for the B2/CsCl-type structured intermetallic materials ScM (M = Ni, Cu, Pt, Hg) to study their elastic, thermal, and ultrasonic features at 300 K. In this study, by means of Born potential model, higher order elastic constants have been carried out for the ScM in their B2 phase. The estimated results of second order elastic constants are employed to enumerate the mechanical features e.g., Lame modulus, Poisson’s factor, Zener anisotropy factor, Pugh’s factor. The ultrasonic velocities alongwith the Debye mean velocity have been estimated for wave passing through intermetallic systems ScM in ⟨100⟩, ⟨110⟩, ⟨111⟩ orientations utilizing SOECs and density. Further, the thermal properties such as thermal conductivity and relaxation time have been found out for the chosen intermetallic systems. Finally, we computed the acoustic attenuation of ScM, which has been enumerate at 300 K based on Akhiezer and thermo-elastic mechanisms. The study of the achieved results concedes the fundamental properties of B2 structured intermetallics ScM.
