Luleå University of Technology is in strong growth with world-leading competence in several research areas. We shape the future through innovative education and ground-breaking research results, and based on the Arctic region, we create global social benefit. Our scientific and artistic research and education are conducted in close collaboration with international, national and regional companies, public actors and leading universities. Luleå University of Technology has a total turnover of SEK 1.9 billion per year. We currently have 1,840 employees and 17,670 students. In the coming years, multi-billion sums will be invested in Norrbotten and Västerbotten in large projects aimed at a more sustainable society nationally as well as globally. Luleå University of Technology is involved in several of these highly topical research projects and the social transformation that follows. We have a wide range of training to match the skills that are in demand. We hope you will help us build the sustainable companies and communities of the future. Materials Engineering is seeking highly motivated candidates for a PhD position to conduct research on a new nickel-based superalloy. As a PhD student, you will be part of a dynamic and international research environment, with close collaboration with industry and leading universities worldwide. Materials Engineering is engaged in extensive research programs spanning a wide range of metallic and ceramic materials. We are part of the Department of Materials Science, which operates under the Department of Engineering Science and Mathematics. The department has several other research topics relevant to materials research (e.g. mechanics of materials, machine elements and strength theory). Subject description Materials technology covers the composition, structure, properties and production of materials, mainly metallic and ceramic materials, as well as their application aspects. Project description This project aims to evaluate a new wrought nickel-based superalloy, ATI 273TM that offers high manufacturability as well as exceptional properties that surpass existing superalloys. The project will systematically study the thermodynamic properties, microstructure, mechanical properties and weldability of ATI 273TM. The goal is to ensure that this superalloy can be seamlessly integrated into the manufacturing processes of aerospace components while maintaining structural integrity and performance throughout the life cycle. The main users of the research results will be aeronautical engineers and manufacturers, who can use the results to design more reliable and efficient aero engines, reducing operating costs and environmental impact. Job duties This PhD position includes both theoretical and experimental work with the goal of improving the understanding and application of nickel-based superalloys in high-temperature materials for the aerospace industry. The research will be applied and interdisciplinary and include laboratory work, modeling and characterization. You will engage in comprehensive thermodynamic characterizations and optimization of heat treatments. Your duties will include conducting experimental studies to optimize heat treatment processes as well as performing detailed microstructural analyzes using advanced microscopy techniques. The project also requires you to assess the mechanical properties and weldability of the ATI 273TM alloy to ensure its practical utility in aircraft manufacturing. The project is carried out in collaboration with GKN Aerospace in Trollhättan, Sweden. As a PhD student, you will be trained in scientific work by publishing scientific articles in reputable journals as well as at national and international conferences. As a doctoral student, you will take both compulsory and optional courses, plan and carry out your research projects independently, and have the opportunity to participate in teaching activities. This position offers extensive experience in both experimental and theoretical aspects of scientific work, furthering your development as a researcher. Qualifications As a candidate, you have theoretical depth and an experimental interest. Thermodynamic and material characterizations are important to this research project. A suitable background for the position is a civil engineering degree with a focus on materials technology, or equivalent. Experience of microstructural and thermodynamic characterization of metallic materials is advantageous. We are looking for a motivated and enthusiastic candidate who can conduct advanced research, work independently and collaborate effectively within a team. Excellent communication skills and fluency in English, both oral and written, are essential. During the evaluation, special emphasis is placed on: • Knowledge relevant to the current project • Communication and collaboration skills • The quality of the thesis • Personal characteristics relevant to research  For further information on specific doctoral education, see study plans for postgraduate education within the Faculty of Technology Information Employment as a doctoral student is time-limited to 4 years, teaching and other department duties can add up to 20% of full time. The workplace is Luleå, Sweden. Intended start date is September 2, 2024.
