Abstract:

Data on the Snoek relaxation in niobium-oxygen alloys, with low oxygen contents, are presented. Through a new measuring technique, it is shown that the internal friction peak is not of the Debye type, even for oxygen concentrations of the order of 550 at ppm. The analysis used, to obtain the relaxation parameters from the internal friction data, is discussed and the procedure used in the paper is compared with others proposed in the literature. © 1993, The Japan Institute of Metals.
