Temperature Variation of the Elastic Constants of Cubic Elements. I. Copper
(1954-09-08)
The ultrasonic pulse technique has been used in conjunction with a specially devised cryogenic technique to measure the velocities of 10-Mc/sec acoustic waves in copper single crystals in the range from 4.2°K to 300°K. The ...
The composite piezoelectric oscillator is employed to measure the adiabatic elastic moduli of crystalline aluminum over the temperature interval 63°K to 773°K.

The composite piezoelectric oscillator is employed to measure the adiabatic elastic moduli of crystalline
aluminum over the temperature interval 63'K to 773 K. The data permit a valid extrapolation to O'K. The
