1. Dynamic and meta-dynamic recrystallization of Ni-based superalloy Haynes 282
Abstract : Thermomechanical processes are a crucial manufacturing step because they can “reset” the microstructure, and set the starting point for all following steps. In turn, the microstructure can be used to tailor the mechanical properties of the material. READ MORE

2. Multiscale modeling of dynamic recrystallization
Abstract : During thermomechanical processing of metals, changes occur in the microstructure of the material which affect its macroscopic properties. By understanding these transformations in the microstructure, it becomes possible to design the processes in a way which yields the desired properties in the finished product. READ MORE

3. Modeling the microstructural evolution during hot working of C-Mn and Nb microalloyed steels using a physically based model
Abstract : Recrystallization kinetics, during and after hot deformation, has been investigated for decades. From these investigations several equations have been derived for describing it. The equations are often empirical or semi-empirical, i.e. READ MORE

5. Modeling the Microstructural Evolution during Hot Deformation of Microalloyed Steels
Abstract : This thesis contains the development of a physically-based model describing the microstructural evolution during hot deformation of microalloyed steels. The work is mainly focused on the recrystallization kinetics. During hot rolling, the repeated deformation and recrystallization provides progressively refined recrystallized grains. READ MORE
