Languages of publication
Substructural strengthening result in preliminary thermomechanical processing, when applied cold deformation with the combination of post deformation annealing and induction hardening based on the of dislocation structure inheritance effect on the mechanical properties such as torsion static strength has been studied. Final heat treatment with the use of post deformation tempering followed by induction hardening and low temperature tempering demonstrated the highest static torsion strength in consequence of the inheritance of polygonal dislocation substructure of ferrite arised at the proper post deformation annealing temperature at preliminary thermomechanical processing by dislocation structure of austenite formed under followed induction hardening heating and then by dislocation substructure of martensite formed result in following quenching.
