“…However, it is often difficult to analyze internal friction spectra because T may be represented by some distribution function rather than a unique value. Since it was known from prior experiments (20,(36)(37) that for the vanadium-niobium alloys charged with hydrogen, the internal friction spectrum is given by a distribution of relaxation times, use of single relaxation analysis procedures would not be applicable. A distribution of T is characterized by an internal friction peak that is wider than the Debye peak (1).…”
