Summary

Internal friction and modulus are a useful probe to examine defects, microstructure and phase transitions as well as important parameters to monitor mechanical behavior. This study focuses a new piezoelectric composite oscillator method for modulus and internal friction measurement. Our improved technique is appropriate to the evaluation of small-size ceramics test piece with 1-3mm thickness, 2-4mm wide and 10-40mm length. Using a LiNbO3 crystal, this technique can be applied to the measurement at elevated temperatures up to 800°C under direct heat environment without buffer materials. For example, the measured data for superconducting YBa2Cu3O7-x wires with 2mm-diameter and 7mm-length indicated an interesting thermal behavior for modulus and internal friction.
