ABSTRACT
Understanding the anisotropic behavior of materials is fundamental for optimizing their performance in various industrial and technological applications. This study investigates the anisotropic nature of ultrasonic wave propagation through titanium carbide (TiC) and titanium nitride (TiN) crystals, two materials of significant interest due to their mechanical and electrical properties. Utilizing theoretical approach starting from nearest neighbor distance and hardness parameter, we systematically characterize the elastic properties and acoustic wave propagation behavior for these crystals using Coulomb and Born-Mayer potentials. By computing ultrasonic wave velocity along different crystallographic directions, we unveil substantial directional dependencies in wave velocity indicative of pronounced anisotropy in both TiC and TiN. Our findings reveal significant directional dependencies in the velocity of ultrasonic waves, indicating pronounced anisotropy in both materials. Through careful analysis, we elucidate the underlying mechanisms contributing to this anisotropic behavior, which stem from the crystal lattice structure and bonding configurations. Beyond fundamental insights, our study underscores the practical implications of these anisotropic characteristics in engineering applications. TiC and TiN have fcc crystal structure and find use in diverse fields such as harden and protect the cutting and sliding surfaces and also in heat shield coating. The directional variations in ultrasonic wave propagation observed in this study have direct implications for optimizing the performance of such applications. This study not only advances the understanding of anisotropic materials behavior but also provides actionable insights for harnessing the unique properties of TiC and TiN crystals in engineering applications.
