Two internal friction peaks discovered in pure aluminum at increasingly low temperatures, respectively by Lax and Filson and by Kosugi and Kino, are interpreted as different occurrences of the very same mechanism responsible for the better-known Bordoni peak, namely the nucleation of thermal kink pairs.
