Effects of strain aging on fracture of low-alloy steels with different structure

Abstract
Low-alloy shipbuilding and pipeline steels are commonly subjected to thermomechanical treatment in order to form a ferrite-pearlite or ferrite-bainite structure. At the same time, a high density of lattice defect appearing in this treatment results in some structural instability fraught with the following aging in the production cycle or during the storage and exploitation. The present paper considers effects of the strain aging on steel fracture mechanism as well as efficient ways to reduce such effects.
