Conclusions

  1. 1.

    Significant thermal stability of the hardened condition of strongly worked low carbon steel is obtained by cyclic deformation by alternating sign bending.

     
  2. 2.

    The effect of stabilization of the hardened condition of strongly cold-worked low-carbon steel is determined by the reduction in integral energy and in volumetric integral of this energy in cyclic deformation. In post-deformation heating softening of the steel additionally retards blocking of the dislocations by impurity atoms supplied by the cementite. As the result processes of both primary and accumulative recrystallization are retarded.

     
  3. 3.

    Preservation of the increased strength of cyclic deforamtion-stabilized cold-worked steel is determined by preservation of the increased dislocation density distributed in the walls of the dislocation fragments and by some decrease in the average ferritic grain size.
