High-temperature internal friction in polycrystalline Zircaloy-4

The high-temperature internal friction spectrum of polycrystalline Zircaloy-4 is investigated in detail, for a wide range of frequencies. Two internal friction maxima are observed. The lower-temperature peak is interpreted in terms of a relaxation mechanism produced by the sliding of particle-free g...
