Young's modulus and internal friction have been measured between 6K and room temperature for several (Hf<sub>1-x</sub>Zr<sub>x</sub>)V<sub>2</sub> alloys (x=0, 0.25, 0.5, 0.75 and 1.0). A V shaped minimum is found in Young's modulus for each of the alloys. For HfV<sub>2</sub> and ZrV<sub>2</sub> the minimum is centred about a temperature at which, as has been confirmed by X-ray diffraction, there is a structural distortion. A peak in internal friction near this temperature is observed and discussed on the basis of current understanding of the structural transformation.
