Papers by Keyword: Snoek Köster Relaxation

Abstract: The mechanical loss spectra obtained in metallic samples covered with various thin films of arachis oils containing different sulphur concentrations, different consistency, and different oil fractions are observed in the low-temperature range from 180 K to 300 K. The observed mechanical loss spectra are identified as the surface induced mechanical loss phenomena. It is demonstrated that mechanical loss spectra are induced by the presence of oil films on metallic substrates. It is shown that the shape, the peak location, and the generation of the constituent low-temperature peaks can be controlled by the state of the arachis oil films.

Abstract: The Snoek-Köster (SK) relaxation and the dislocation-enhanced Snoek Effect (DESE) in deformed ultra-high purity Fe-C alloys and industrial low-carbon cold-rolled steel sheets as well as a quantitative comparison between experimental data and computer simulations have been presented.
