In Situ Study on Interrupted Growth Behavior and Crystallography of Bainite

The growth behavior and crystallographic orientation of bainite in a low carbon steel were investigated by a combination of in situ observation and electron backscattered diffraction. The intersection of different bainitic ferrite (BF) laths was analyzed in detail. The results show that the growth of a given lath stops when it runs into a preexisting lath of bainitic ferrite. Growth resumes, after a short stasis, through the nucleation of a new …
