Abstract
Splitting,i.e., delamination behavior in Charpy specimens of low-carbon steel was found to be caused by cracks propagating between pancake grains parallel to the rolling plane of the as-rolled plate. The results suggest the mechanism is a decohesion of grain boundaries that is independent of the texture of the material. The number of splits increased with decreasing finishing temperature and impact test temperature. The energy absorbed in impact testing was inversely proportional to the number of splits. In specimens annealed after rolling splitting was evident until the material was almost completely recrystallized.
