Material evaluation method by acoustic velocity measurement |
摘要 |
All independent acoustical physical constants (elastic constants, piezoelectric constants, dielectric constants and density) of a material are predetermined as a function of its chemical composition, and the calibration line between the acoustic velocity for each of the substrate crystal plane, the propagation direction and the propagation mode, and other chemical and physical properties is numerically calculated with ease without making any experiments.
