In line with market demands of automotive sector on lighter and lower CO₂ footprint materials; the interest on advanced high strength steels (AHSS), particularly in dual phase (DP) steels has been gradually increasing. The presence of hard and soft phases in DP microstructure provide these steels a balance of high strength and ductility, which then permits a wide range of utilization areas. Amongst many DP steel grades in market, cold rolled DP steels are conventionally produced by continuous annealing lines in the world. On the contrary, this study handles the development of an alternative route apart from conventional annealing methodologies, which includes intercritical annealing in batch annealing furnaces. Determination and modelling of batch annealing process parameters for cold rolled steel sheets is crucial to obtain target steel microstructure and hence mechanical properties and formability of desired DP steel grade. Critical annealing temperature, isoholding time and cooling rate ranges were estimated with computational metallurgy and were also validated via dilatometry and physical annealing trials on cold rolled steel sheets. The applicability of annealing parameters at industrial process conditions were also taken into account. Annealed steel sheet samples were characterized through various microstructural analyses and mechanical tests. Results agreed well with computational outputs, specifications and formability expectations of DP steel grades. Examination under scanning electron microscope and optical microscope showed that there were mainly ferrite phases and martensite/austenite islands in the microstructure. In conclusion, holistic evaluation on all study results indicate that modelled batch annealing route and parameters of this study can be an alternative and innovative methodology for cold rolled and annealed DP flat steel manufacturing with lower CO₂ footprint and cost compared to conventional production methods.
