Abstract The elastic, thermal and ultrasonic properties of zirconium nanowire (Zr-NW) have been investigated at room temperature. The second and third order elastic constants (SOECs and TOECs) of Zr-NW have been figured out using the Lennard–Jones Potential model. SOECs have been used to find out the Young’s modulus, bulk modulus, shear modulus, Poisson’s ratio, Pugh’s ratio, Zener anisotropic factor and ultrasonic velocities. Further these associated parameters of Zr-NW have been utilized for the evaluation of the Grüneisen parameters, thermal conductivity, thermal relaxation time, acoustic coupling constants and ultrasonic attenuation. On the basis of the above analyzed properties of Zr-NW, some characteristics features of the chosen nanowire connected with ultrasonic and thermo-physical parameters have been discussed.

通过弹性、热和超声分析研究锆纳米线

摘要 研究了室温下锆纳米线 (Zr-NW) 的弹性、热学和超声性能。Zr-NW 的二阶和三阶弹性常数（SOEC 和 TOEC）已使用 Lennard-Jones 势模型计算得出。SOEC 已被用于找出杨氏模量、体积模量、剪切模量、泊松比、Pugh 比、齐纳各向异性因子和超声波速度。此外，Zr-NW 的这些相关参数已用于评估 Grüneisen 参数、热导率、热弛豫时间、声耦合常数和超声衰减。在以上分析Zr-NW特性的基础上，讨论了与超声和热物理参数相关的所选纳米线的一些特性。
