Abstract:
Mechanical properties of chromium-nickel-molybdenum steels with the carbon contents of 0.1 to 0.4\% after slow continuous cooling in the bainitic range have been determined, and the structure has been investigated. It has been shown that, at a carbon content of about 0.10-0.15\% and upon additional alloying with silicon and aluminum after such a heat treatment, in steels, the structure of carbide-free bainite is formed and a substantial enhancement in the impact toughness is observed compared to bainite containing carbide precipitates. The enhancement in the level of toughness is related to the presence in carbide-free bainite of an appreciable amount of retained austenite enriched with carbon.
