“…Good reliability and accuracy of the hot and cold rolling processes was confirmed in (Kuziak and Pietrzyk, 2011;Madej et al, 2015). Since the final product properties are obtained either during laminar cooling or during continuous annealing, validation of the phase transformation model during these processes is essential.…”

Fast progress in modeling of metal processing encourage researchers to look for better technologies, which can be done through optimization of their design. Authors have developed the computer system ManuOpti for optimization of manufacturing chains based on materials processing. Application of this system to simulations and optimization of manufacturing of automotive parts was the general objective of the paper. ManuOpti software enables performing optimization by the user with little experience in the computer science and in the optimization methods. On the other hand, the application of the optimization techniques is efficient only when reliable material models and accurate numerical methods are applied. Therefore, validation of models describing microstructure evolution in automotive steel (Dual Phase-DP) was the next objective of the paper. Physical simulations of thermal cycles were performed and the experimental results were used to validate the model. Numerical tests with the ManuOpti system recapitulate the paper. Case studies for the tests included various thermal cycles of the continuous annealing of DP steels.

Microstructure-based numerical modeling of the deformation heterogeneity and ferrite recrystallization in a cold-rolled dual-phase (DP) steel has been performed by using the crystal plasticity finite element method (CPFEM) coupled with a mesoscale cellular automaton (CA) model. The microstructural response of subsequent primary recrystallization with the deformation heterogeneity in two-phase microstructures is studied. The simulations demonstrate that the deformation of multi-phase structures leads to highly strained shear bands formed in the soft ferrite matrix, which produces grain clusters in subsequent primary recrystallization. The early impingement of recrystallization fronts among the clustered grains causes mode conversions in the recrystallization kinetics. Reliable predictions regarding the grain size, microstructure morphology and kinetics can be made by comparison with the experimental results. The influence of initial strains on the recrystallization is also obtained by the simulation approach.

The article presents a comparison of the hole-flange factors for four steel sheets which have different strength parameters. Three types of punches were applied in the research: cylindrical, spherical and conical. The holes in the samples were made with the use of the following cutting technologies: laser cutting, electrodischarge method using wire and punching. The coefficient of the hole expansion shows that the shape of the used tools has a great impact on the final diameter of the hole. The greatest enlargement of the diameter was obtained for the conical punch, a smaller enlargement for the spherical one and the smallest enlargement for the cylindrical punch. The results of the hole expansion tests using the conical punch diverge from the general rule saying that the greater the plastic deformation of the sheet metal during tensile tests, the more you can enlarge the hole before cracking appears.
