The piezoelectric ultrasonic composite oscillator technique (PUCOT) was used at frequencies in the range 40 to 150 kHz to measure dynamic Young's modulus for short-length single crystals of copper at temperatures in the range 25 to 650°C and for poly-crystalline copper at room temperature. Corrections to the modulus for variations in l/d (length/diameter) resulted in no loss of precision due to wave velocity dispersion.
