Understanding dislocation structure
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.
We are searching for enthusiastic candidates holding an MSc degree in physics, chemistry, materials science, or a similar field. The candidate must have knowledge of physics of materials, solid state physics, solid-solid phase transformations, and mechanical behaviour. Moreover, the candidate should have:
• affinity for computational calculation as well as a solid background in mathematics and numerical methods.
• an “academic attitude” with excellent analytical skills, initiative, inventiveness, curiosity, and critical thinking about the research approach and results.
• strong communication skills (high degree of English proficiency), ability to integrate, and good social behaviour.
Delft University of Technology (the TU Delft) is a multifaceted institution offering education and carrying out research in the technical sciences at an internationally recognised level. Education, research and design are strongly oriented towards applicability. The TU Delft develops technologies for future generations, focusing on sustainability, safety and economic vitality. At the TU Delft you will work in an environment where technical sciences and society converge. The TU Delft comprises eight faculties, unique laboratories, research institutes and schools.
Mechanical, Maritime and Materials Engineering
The Department of Materials Science and Engineering (MSE) of Delft University of Technology, undertakes coherent and innovative research dedicated to developing, producing, characterising, and manipulating materials, with a focus on metals. The aim is to develop fundamental understanding forming the basis for better performance and a longer life cycle with preservation of functionality, while at the same time optimising sustainable use of resources and minimising the environmental footprint.
The Microstructure section of the MSE Department, with five senior scientists and some 15 PhD students and post-docs, has a leading position worldwide in the field of microstructure control, based on both experimental characterisation and physical modelling.
