Abstract

The parameters of the interaction of nitrogen atoms with dislocations by amplitude-dependent internal friction (ADIF) behavior of single crystals of a nitrogen-containing austenitic stainless steel in a wide temperature range are estimated. A number of models were proposed to explain the nature of ADIF in alloys. In the vicinity of 700 K nitrogen atoms become mobile on a scale of the characteristic times of changing the external elastic stress or the Snoek-type relaxation process, and a number of nitrogen atoms being dragged by mobile dislocations increases with increasing temperature.
