T1 - Temperature dependence of the propagation speed of a longitudinal wave in different solids for use as a wedge material in an extreme temperature resistant ultrasonic transducer N2 - In special cases of angle beam ultrasonic measurement the applied transducer has to withstand extreme temperatures. Since the irradiation angle depends on the speed of sound in both the wedge material and the tested object, the developer must take into account the speed of Sound in a wedge material over the whole temperature range of transducers application.
