High Temperature Resonant Ultrasound Spectroscopy: A Review

[摘要] The measurement of elastic constants plays an important role in condensed matter physics and materials characterization. This paper presents the resonant ultrasound spectroscopy (RUS) methodfor the determination of elastic constants in a single crystal or amorphous solid. In RUS, the measured resonance spectrum of a properly prepared sample and other information such as geometry,density, and initial estimated elastic constants are used to determine the elastic constants of the material. We briefly present the theoretical background and applications to specific materials; however,the focus of this review is on the technical applications of RUS, especially those for high-temperaturemeasurements.
