摘要 The influence of technological parameters of controlled rolling and accelerated cooling (TMCP-processing) on microstructure and mechanical properties of plates with thickness of 25 mm and more at the mill "5000" of OJSC "Мagnitogorsk Iron and Steel Works" were investigated.The necessity of formation of fine-grained ferrite-bainite microstructure without elongated areas of coarse lath bainite for achievement of DWTT properties is proved.Precipitation conditions and type of Nb(C,N) and (Nb,V)(C,N) particles with the size of less than 10 nm in the process of rolling and additional tempering are defined.
