Elastic Constants of Cadmium from 300° to 575°K

Abstract
The adiabatic elastic constants of single‐crystal cadmium have been determined by means of the ultrasonic pulse‐echo technique over the temperature interval from 300° to 575°K. The values obtained at 300°K are C11 = 11.45, C33 = 5.085, C66 = 3.750, C44 = 1.985, and C13 = 3.99 in units of 1011 dyn/cm2. The temperature dependences of the linear compressibilities, the Grüneisen parameter, and the lattice contribution to the specific heat have been calculated using the elastic constants obtained in the present study and other necessary thermal data available in the literature.
