The resonance method of three-dimensional free vibrations with the cylindrical specimen, which had been developed by the authors, was applied to determine the elastic constants of polycrystals in a temperature range of 4-300 K. The temperature dependence of elastic constants of pure aluminum agreed well with the published data measured by the ultrasonic-pulse-echo technique over the temperature range of measurements. The sluggish change induced by the magnetic transformation could also be detected in niobium. In addition, the temperature dependence of elastic constants for superconducting Al-Si and Al-Ge supersaturated solid solutions was examined, and also the Debye temperature could be determined by extrapolating the elastic constants to the values at O K.
