Abstract
Low frequency elastic and anelastic properties of Cox(CaF2)100−x (x = 41 ÷ 84 at.%) nanocomposites have been studied within a temperature range of 170–730 K. The dominated contribution of elastic energy dissipation in a metal phase to a low frequency internal friction (Q−1) in composites has been revealed. The observed peculiarities of Q−1(T) dependences are discussed.
