摘要: The temperature dependence of internal friction (T−tan curves) in pure aluminium (Al) is measured at sixteen different frequencies. Based on T−tan curves, the frequency (f−tan also obtained by interpolation method. An peak observed both curves and f−tan curves. activation energy found to be 2.08±0.02 eV compared value 1.60±0.04 It suggested that change relaxation strength with should considered when one calculates
