Investigation of Thermal and Ultrasonic Properties of (Mg2La, Mg2Nd, Mg2Sm) (C14) Phase of Intermetallic Compound
Main Article Content
Abstract
In this study, the physical characteristics of the hexagonal closed-packed structure's Mg2La, Mg2Nd, and Mg2Sm (C14) phases at 300 K have been examined. The L-J potential approach was used to compute SOECs and TOECs. The obtained SOECs and TOECs are utilized to assess mechanical characteristics at various angles along the unique axis. Thermophysical properties of the material at 300K have been evaluated, such as energy density, thermal conductivity, Debye temperature, and Debye average velocity of selected materials. Beyond this, we have computed the ultrasonic acoustic coupling constant at room temperature. Ultimately, the thermoelastic relaxation process and phonon-phonon interaction are used to obtain attenuation. The obtained results have been compared with previous research on similar kinds of HCP metal.
Keywords:
Mg2La, Mg2Nd, and Mg2Sm (C14) Phase intermetallic compound, Debye temperature, ultrasonic properties, thermal conductivity.
