Temperature characterisation of material using SAW

This work approaches the elastic properties of nonpiezoelectric materials and reports their temperature dependence for a duraluminium substrate. The method is based on the propagation time measurement of ultrasonic Rayleigh waves and attenuation of electrical voltage between emitter and receiver. Transducers made of P(VF/sub 2/-VF/sub 3/) polymer film are used for SAW (Surface Acoustic Waves) generation and detection.
