The properties of low-carbon experimental steels are studied within which a structure of predominantly ferrite-bainite to bainite-martensite is obtained with variation of heating and cooling conditions. The effect of bainite of different morphology on such properties as strength, impact strength and steel deformation capacity is demonstrated. It is established that steels within whose structure there is globular bainite with comparable strength values have a lower ductile-brittle transition temperature than in the presence of acicular bainite.
