1. Creep modelling of particle strengthened steels
Abstract : Materials to be used in thermal power plants have to resist creep deformation for time periods up to 30 years. The role of alloying elements for creep strength of 9-12% Cr steels is analysed. The creep strength in these steels relies on minor additions of alloying elements. READ MORE

2. Modeling the microstructural evolution during hot working of C-Mn and of 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. 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

5. Creep modelling of particle strengthened steels
Abstract : Materials used in thermal power plants have to resist creep deformation for time periods up to 30 years. Material evaluation is typically based on creep testing with a maximum duration of a few years. This information is used as input when empirically deriving models for creep. READ MORE
