Abstract :
Thermal errors of time-resolved ultrasonic material characterization systems are considered. For V(z) data acquisition configuration, theoretically estimated the thermal error coefficient of leaky wave velocity was found to be 10-3 1/°C. It was shown that the reading of the sound velocity in immersion liquid is not required for V(x) data processing. The thermal error coefficient estimated experimentally in 20-50°C range with the developed V(x) system is 5·10-5 1/°C for a water-fused quartz interface
