This paper studies the effect of processing history on grain boundary misorientation angles in steels and investigates the relationship between microstructure and impact transition behaviour. For normalised steel, fracture is directly related to the metallographic two-dimentional microstructure, however, for thermomechanical. controlled rolling steel grain boundary misorientation needs to be taken into account.
