Transmission electron diffraction microscopy is used to analyze strain hardening of steel with a bainitic structure. Contributions to strengthening are considered for lattice friction, interphase boundaries, dislocation substructure, carbide phases, alloying element atoms, and remote stress fields. It is established that substructural and solid solution strengthening make the greatest contributions. The reason for steel loss of strength with large degrees of deformation is connected with activation of deformation microtwinning.
