Functieomschrijving

Plastic deformation of metals causes a significant increase of the dislocation density, and thus of the defect energy in the material. During subsequent annealing, softening takes place by three processes: recovery, recrystallisation and grain growth. All three can also occur dynamically, i.e. during hot deformation. The aim of the project is to develop physical understanding of the development of the dislocation structure during recovery, to understand nucleation in recrystallisation in relation to the dislocation structure and to determine the influence of chemical composition on grain growth. Based on this understanding, the softening processes in steel on the microstructural scale will be described in physically based models. The essentials of the physical models are to be captured in a simplified on-line model for application during the production process.
