Abstract
Measurements of the kinetics of extrinsic grain boundary dislocations (EGBDs) when spreading and investigations of the microstructure of 0.12C22Cr17Ni austenitic steel subjected to different variants of thermal treatment are presented. Diffusional properties of grain boundaries (GB) were studied by the statistical distribution of activation energy for each state of the material. It was found that the distribution shifts towards higher values when the annealing temperature rises. The discussion deals with the structural and chemical factors responsible for the effects observed. The processes of grain growth, recovery of GB structure, secregation and precipitate dissolution have been taken into consideration.
