Micromechanical evaluation of intergranular crack growth under continuous casting conditions
Most steel grades undergo a ductility trough in the temperature range 700 to 1100 °C that may bring about surface cracks in the CC strands. 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.
