Abstract—The fracture profiles and distribution of the microhardness in regions adjacent to the fracture surface in the region of tension of Charpy samples of the high-viscous 08G2B steel (0.08 C; ~2 Mn; 0.2 Mo; ≈0.15 Σ(Ti–V–Nb); 0.004 N; 0.04 Al; 0.004 S; 0.007 P wt %) with a filamentary structure formed by non-recrystallization controlled rolling with an accelerated cooling have been studied. The factors that provide the extremely high impact toughness of steel in the case of the fracture of the Charpy samples perpendicular to the surface of filaments have been revealed.
