AN OVERVIEW OF RECENT PROCESSES AND ARGUMENTS ON BAINITIC TRANSFORMATION THEORY

The main points of view about shear and difusion for the bainitic transformation, which include some important research results and key controversial points,i.e., bainite definition, incomplete phenomenon, solute-drag and solute drag-like effects,the shape, characteristics,nature of the surface relief,crystallography,initial carbon content in bainitic ferrite, the so-called midrib of bainite, source and formation model of lower bainitic carbide,etc., were briefly reviewed
