摘要

摘要提出了在金属微晶棒中形成超声波信号的理论模型，其中考虑到了微晶棒缺陷态的可变行为。分析了在快速动力学超声波实验中，样品缺陷结构的可迁移状态对其共振频率变化特征的影响。解释了在这种过程中杨氏模量的降低。以铝合金 D16 棒的共振声学振动为例，证明了理论数据与实验数据之间的对应关系。

Influence of Fast Dynamics Effects on Resonant Ultrasonic Vibrations of Polycrystalline Metal Rods

Abstract

A theoretical model for the formation of ultrasonic signals in metallic microcrystalline rods taking into account the metastable behavior of their defective states is proposed. The influence of metastable states of the defective structure of samples on the features of changes in their resonant frequencies in ultrasonic experiments of fast dynamics is analyzed. The decrease in Young’s modulus in such processes is explained. The correspondence between theoretical and experimental data is demonstrated for the example of resonant acoustic vibrations of rods made of aluminum alloy D16.
