Rudyuk, I. Mikhailova, Yu. Tomenko] Conclusions: 1. The level of crack resistance of cast hypereutectoid steels is determined by the size of the inclusions of eutectic cementite which depends solely on the amount of carbon contained in the steel. Alloying with 0.86-1.72% Cr, 0.9-1.32% Ni and 0.16-0.3% Mo does not affect the amount of eutectic cementite, and has practically no effect on the level of crack resistance when the steel contains 0.90-1.00% C; it decreases somwhat when the carbon concentration increases to 1.80-1.90%. 2. Heat treatment (quenching in air from 920°C, tempering at 550°C) raises the level of crack resistance of chrome-molybdenum and chrome-nickel-molybdenum steels. The effect manifests itself the more strongly, the higher the degree of alloying of the steel with carbide forming elements is (with 0.9-1% C). 3. The optimal combination of hardness and dynamic crack resistance after heat treatment of specimens is attained in hypereutecoid alloy steels when the carbon content is slightly higher than the eutectoid concentration. This has to do with the complete dissolution of excess cementite and the formation of special globular carbides. The same combination of properties can be ensured in steels with higher carbon content by raising the degree of alloying of the steel with carbide forming elements.
