Abstract
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 0°K. The Debye characteristic temperature of aluminum at 0°K, computed with these data, is 439°K. Various novel procedures designed to facilitate the use of the method are described.
