Resumo
The amplitude dependence of the internal friction (ADIF) of zirconium and Zr–8.1% Nb and Zr–20.2% Nb alloys has been investigated after different heat-treatment regimes. ADIF components caused by the processes of enhanced dissipation of energy at twin boundaries and at the boundaries of ω–β phases under mechanical vibrations have been revealed. The effect of twins, athermal, and isothermal ω phases, and the dislocation structure on the ADIF has been analyzed. A comparative analysis of the studied materials and their states in damping ability has been performed.
