Abstract

The microstructure and hardness of steel 20 are studied in the range of healing of an artificially created internal crack. In the range of healing of the crack the microstructure is represented primarily by ferrite. The ferrite grains grow through the boundary of the internal crack and contain polyhedral subgrains several hundred nanometers in size. The hardness of the ferrite in the range of healing of the internal crack is higher than in the matrix. A possible cause of this is substructural hardening.
