Abstract

The morphology, crystallography, microarea orientation, and carbon distributing state of the lower bainite midrib observed in three silicon contained steels were studied by means of trans- mission electron microscopy (TEM), electron microdiffraction technique, and electron energy loss spectroscopy (EELS). New experimental information on the orientation and carbon con- centration differences between the midrib and the surrounding bainitic ferrite matrix was ob- tained. The nature of the midrib in connection with the transformation mechanism of lower bainite is discussed.
