Abstract:

In this paper we consider the aging mechanism of pipe steels as a hierarchical process of displacement of carbon atoms and the formation of carbide inclusions at the grain boundaries. It is shown that a realistic estimate of the pipe steel aging time is determined by the collective interaction of the impurity atoms and dislocations.
