The Morphology of Intermediate Structures Formed During Bainite Transformation in HSLA Steels

[摘要] The paper deals with the structure of bainite formed under the influence of thermal deformation cycles of welding in low-carbon bainitic class steels. Morphology features associated with the formation of mesoferrite and granular bainite determines the high cold resistance of welded joints.
