Abstract
Internal friction peaks P1, P2 and P3 were determined by the composite oscillator technique (APUCOT) at 40 and 120 kHz in unalloyed Zr + H and in Zr-2.5Nb + H. The effect on the peaks of hydrogen content, thermal cycling and ageing was investigated. Pl can be increased by misfit dislocations due to hydrides. The height of P2 is proportional to the total content of hydrogen while P3 depends on the hydride morphology.
