Abstract

The internal friction of room temperature deformed zirconium is studied in the temperature range of 80 to 300 K and at a frequency of about 80 Hz. A non‐linear least squares fit is used to analyse the damping spectra. Not less than five peaks are unveiled by this procedure, for the specimen s in the deformed state. Two of the peaks are interpreted in terms of a dislocation relaxation proce s while the other three are related to the presence of residual hydrogen in the specimen.
