The adiabatic elastic constants of magnesium single crystals have been measured by an ultrasonic pulse technique. The values at 298^ are in good agreement with the recent values of Long and Smith. The values extrapolated to 0^ are c₁₁=0. 635, c₃₃=0. 664, c₄₄=0. 1842, c₁₂=0. 259, c₁₃=0. 217 in units of 10^12 dynes/cm^2. A Debye characteristic temperature, , of 3883^ has been calculated at 0^ by averaging the inverse cube of the longitudinal and transverse elastic wave velocities over all directions of propagation. Atomic force constants for a central-force model with an electron gas term are also obtained.
Slutsky et al. (1957) studied this question.
