Most steel grades undergo a ductility trough in the temperature
range 700 to 1100 °C that may bring about surface cracks in the CC
Micro-mechanical modelling of the as solidified austenite-ferrite
microstructure, supported by experimental evaluations of the fracture
surfaces, affords a comprehensive description of the crack formation
mechanism. This opens the way for a quantitative evaluation
of the sensitivity of CC strands to transverse cracks.
