Manufacturing of dual phase (DP) steels products is a complex process. Application of special thermal cycles during continuous annealing is one of the methods of obtaining DP microstructures. Development and validation of the numerical model for the continuous annealing of DP steels was the objective of the paper. Experimental part include dilatometric tests and physical simulations of various thermal cycles characteristic for the continuous annealing. The former were combined with the inverse analysis and were used for identification of the model. The latter supplied data regarding microstructure and properties after various annealing cycles. Numerical tests of the model confirmed its good predictive capabilities.
