摘要	A model has been developed to describe the formation of the carbon atmosphere around dislocations during the aging of a bake-hardenable steel, by taking into account the concurrent segregation of carbon atoms to dislocations, grain boundaries, and pre-existing cementite particles. The effects of the segregation of carbon to grain boundaries and to pre-existing cementite particles on the formation of the carbon atmosphere have been discussed theoretically. Strain-aging experiments have been carried out with a vacuum-degassed ultra-low-carbon blake-hardening steel, and the experimental results been compared with the theoretical predictions. It is shown that the model developed can describe the formation of the carbon atmosphere around dislocations in both low-carbon and ultralow-carbon bake-hardenable steels in industrial processing conditions.
