1. 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

2. 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

4. On impacts and ride-through of voltage sags exposing line-operated AC-machines and metal processes
Abstract : During the last decade, power quality has been recognised asa global problem. Among different types of power qualityproblems, voltage sags have been identified to be one of themost severe problems for different process industries. The mostcommon reason to voltage sags is lightning strikes in powerlines. READ MORE

5. Tribology in Metal Working
Abstract : This thesis focuses on the tribological performance of tool surfaces in two steel working operations, namely wire drawing and hot rolling. In all forming operations dimensions and surface finish of the products are of utmost importance. READ MORE
