LTU - Lulea University of Technology
Lulea, Sweden
The Division of Materials Science at Luleå University of Technology are looking for a researcher who is interested in conducting research in Engineering Materials, focusing on the design and processing of hydrogen diffusion permeation barriers for steels. The research subject “Engineering Materials” has ongoing research programs span broad research areas in metallic and ceramic materials (high-temperature intermetallic, space materials, high-strength steels, porous ceramic materials, and materials intended for energy recovery).
Subject description
Engineering materials includes the field of material composition, structure, properties and production of materials – mainly metallic and ceramic – as well as application aspects.
Project description
The project, design and processing of hydrogen permeation barriers, focuses on designing complex, concentrated alloys (CCAs) as hydrogen permeation barriers through thermodynamic modeling and synthesis in amorphous and crystalline states as coatings and powders. The CCAs will be characterized for hydrogen diffusion pathways and resistance to hydrogen embrittle at high pressures. The design of CCAs focuses on tailoring local disorder, formation of nano-twins, controlling the grain size, a large number of solute atoms, tailoring grain boundaries, and concentration of imperfections during processing to tailor sorption capacity and resistance to hydrogen embrittlement of the CCA powder. The CCA powder will be coated using laser processing on low alloy steel to demonstrate resistance to hydrogen embrittlement in steels. Process analysis and imperfection mitigation while maintaining the material properties to produce high quality surfaces is an essential aspect of the laser processing.
Duties
Working as a researcher involves defining your daily tasks and how they will be carried out. You will act and train as a project manager, combined with your development. Involvement with other projects and teaching will occur up to 20 percent of your time.
Qualifications
The candidate must have a doctoral degree in materials science, chemistry or chemical engineering, good knowledge, experience, and a good publication report on CCA alloys and hydrogen permeation measurements. The candidate must be good at written and oral English. Experience in processing science, porous materials, and synthetic chemistry is advantageous.
