A study has been made of the effect of dynamic strain-ageing on the initiation and propagation of ductile fracture in mild steel. Grain boundary carbide cracking has been found to contribute to void formation in the tempereture range 77Β°K to 573Β°K. Using scenning electron microscopy it hes been show
In the transition regime plain strain crack propagation in ferritic steels proceeds by a combination of cleavage and ductile rupture processes, the latter being confined to ligaments that are parallel to the direction of macroscopic crack propagation. These ligaments rupture as the crack propagates,
