Elastic Constants of Zinc from 4.2°K to 77.6°K

The adiabatic elastic constants of zinc single crystals have been measured by an ultrasonic pulse technique. The values extrapolated to 0^∘{}K are: c₁₁=1.770, c₃₃=0.685, c₄₄=0.459, c₁₂=0.348, c₁₃=0.528 in units of 10¹² dynes/cm². A Debye characteristic temperature, θ, of 327^∘{}±{}5^∘{}K has been calculated at 0^∘{}K by averaging the inverse cube of the longitudinal and transverse elastic wave velocities over all directions of propagation.
