| Abstract: | By means of thermal simulation, the granular bainite transformation process in the weld metal of 15MnVN steel has been investigated. It is revealed that the granular bainile transformation process can be derided into five steps, i.e., the formation of the ferrite nuclei, the growth of the ferrite in the longitudinal direction, the growth of the ferrite in the transverse divection the intersetion of the ferrite, and the contraction of the remaining austenitic islands, |
