Abstract
A peak in the internal friction due to dislocations in aluminum was found well below the temperature of the usual Bordoni peak. Measurements were made from 25 kc to above 1 Mc, yielding a relaxation peak that varied with frequency over a temperature range of 21°K to 31°K. The activation energy of this peak was found to be 0.024 ev.Keywords
