KTH Royal Institute of Technology

KTH Royal Institute of Technology in Stockholm has grown to become one of Europe’s leading technical and engineering universities, as well as a key centre of intellectual talent and innovation. We are Sweden’s largest technical research and learning institution and home to students, researchers and faculty from around the world. Our research and education covers a wide area including natural sciences and all branches of engineering, as well as architecture, industrial management, urban planning, history and philosophy.

Project description

Third-cycle subject: Engineering materials science

The demand for stainless steel is increasing at a rate of 5-6% per year worldwide. For Sweden, who owns a share of almost 60% of the world’s duplex stainless steel (DSS) production, this means a need of robust and cost-effective production process to meet the demands of their respective customers. One of the serious problems that occurs during production of DSS and which needs to be addressed is corner cracks during continuous casting, both transverse and longitudinal. They require costly grinding operations or, at worst, scrapping resulting in extra cost.

In this project the materials explanation for these phenomena will examine the resulting cast structure and correlating variations in crack behavior with variations in microstructure, composition and process parameters such as casting speed and cooling rate. To achieve this, the dendritic structure and composition variations resulting from segregation will be simulated by SWERIM with a state of the art phase field (PF) model to pinpoint the factors that control cracking. The results will be validated with laboratory experiments and plant trials in two different continuous casting plants. Finally, a set of guidelines will be developed based on simulations and experiments to achieve better process control during continuous casting, thereby reducing the risk of corner cracks.

The candidate will work in close cooperation with other researchers from SWERIM and industry companies. The candiate must be able to work as part of a research group. The project requires a substantial amount of experimental work followed by data analysis, which the candidate will be responsible for. A critical review of literature and data collected in the project will make up an essential part of the project. Motivation, creativity and analytic problem solving are important characteristics in a candidate.

What we offer

The Division of Processes at the Department of Materials Science and Engineering focuses on research on the development and optimization of processes with respect to cleanness, energy efficiency and environment

  • passed a degree at advanced level,
  • completed course requirements of at least 240 higher education credits, of which at least 60 higher education credits at advanced level, or
  • in any other way acquired within or outside the country acquired essentially equivalent knowledge.

Selection

In order to succeed as an doctoral student at KTH you need to be goal oriented and persevering in your work. In the selection of the applicants, the following will be assessed:
