Abstract
Internal friction of hydrogenated Ti, Ti-6A1-4V, Ti-5Al-2.5Sn and Ti-50Nb alloys in the range of 100 K to 350 K was measured. It was found that there was not only a known Snoek peak of hydrogen atoms in the β-phase, but also a new relaxation peak caused by the small amount of hydrogen atoms in the h.c.p. lattice α-phase. The mechanism, by which this new peak is produced, is suggested.
