Conclusions

  1. 1.

    The temperature relationship of impact strength of N26T3 steel correlates with the relationship of the length of zone L located close to the source of fracture and having a wrinkled microrelief with elongated pits.

  2. 2.

    In impact fracture of hardened N26T3 steel the quantity of α-martensite within the limits of the zones of plastic deformation remains constant despite the existing gradient of deformation of the material in these zones.

  3. 3.

    The thickness of the strongly deformed microzone of plastic deformation depends upon the microrelief in the center portion of the fracture and the thickness of the weakly deformed macrozone upon the stressed state of the material at fracture.
