Conclusions

  1. 1.

    In the steel investigated brittle fracture is accompanied by crystalline components in the fracture due to the presence in the microstructure of phases with sharply differing microhardnesses and the precipitation of finely dispersed carbides in the boundaries between austenite and σ-ferrite and between martensite and σ-ferrite.

  2. 2.

    The fracture of the structure consisting of martensite and σ-ferrite is brittle in dynamic tests and the crystal facets of the fracture are due to transcrystalline fracture of martensite.
