Abstract
An investigation on the Snoek-Köster peak in high purity iron doped with 1000 at ppm of carbon was carried out. The study of the influence of low temperature deformation on the S-K peak revealed that screw dislocations may not play the major part in the S-K relaxation in α-Fe. The carbon S-K peak's parameters were found to be HSK = 1.84 ± 0.03 eV and τ°SK = 0.7 x 10-19 s-1. It was also found that carbon-vacancy pairs might influence the S-K relaxation. However these experiments are not considered as an evidence in support of Mondino and Seeger's interpretation. The β2 and βγ peaks were also observed.
