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. Microstructural Evolution In As-cast Alloys during Plastic Deformation
Abstract : The effect of deformation on microstructural changes in metals and alloys is the subject of considerable practical interest. The ultimate goal is to control, improve and optimize the microstructure and texture of the finished products produced by metal forming operations. 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. Hot working of powders : procedure and products
Abstract : This dissertation can be divided into two main parts. The first deals with the hot working conditions of mild steels in powder forging, the second with the deformation behaviour of powder forged products; both monolithic and compound parts are studied. READ MORE
