摘要：
Known investigations of dual phase ferritic-martensitic steels contain very limited information on the characteristics of toughness and cold resistance, the role of which increases with an increase in cross section of the parts used. This paper was done on laboratory heats of steels. The base for the tests was type 10Kh1MF steel, which was heat treated to form ferritic-pearlitic and ferritic-martensitic structures. The ferritic-pearlitic structure was obtained by annealing at 950 degree C. The treatment for the ferritic-martensitic structure consisted of preliminary normalizing (950 degree C, 1 h) subsequent hardening (790 degree C for 30 min, water quench) from the intercritical temperature range.
