Internal friction in hydrogen-charged palladium

摘要: The work has been suggested by the fact that in pure metals with dislocations, point defects, such as impurity atoms, may give rise to thermally activated elastic relaxation effects. Palladium chosen metal basis and hydrogen interstitial because palladium is absorbent of hydrogen, which be introduced an electrolytical process degassed opposite process, without any change dislocation density material. experiments show electrolytic charge atoms order 0.4.10-3 per atom modify theQ−1(T) curve permanently strained material at low temperatures. characteristic effects due motion (Bordoni peaks) disappear, while a new introduced. A structural explanation proposed based on interaction mechanism between impurities dislocations.
