To study the damping mechanism of dislocation relaxations in aluminum, internal friction of a high purity aluminum crystal was measured for the frequency of 50 kHz at the temperatures between 2 and 240 K. There were three temperature regions of dislocation peaks, i.e. the Bordoni relaxation (Bordoni
