Inheritance of misorientations and model of formation of bainite structure in low-doped steels under the influence of austenite deformation

The structure and spectra of misorientation in carbide-free bainite low-carbon low-doped pipe steel are studied. It is demonstrated that the increase in the portion of low-angle misorientations in deformed steel is due to the fact that bainite inherits the deformation structure of austenite. A model...

Description
Summary:The structure and spectra of misorientation in carbide-free bainite low-carbon low-doped pipe steel are studied. It is demonstrated that the increase in the portion of low-angle misorientations in deformed steel is due to the fact that bainite inherits the deformation structure of austenite. A model of computation of the kinetics of bainite transformation of deformed austenite is proposed which facilitates forecasting of the average size of structural element with preset misorientation depending on the mode of thermomechanical treatment.
