Subject description Materials Engineering is looking for highly motivated candidates for a PhD position to perform 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 Science and Engineering is engaged in extensive research programs spanning a wide range of metallic and ceramic materials. We are part of the Division of Materials Science, which operates under the Department of Engineering Sciences and Mathematics. The department has several other research topics relevant to materials research (e.g. mechanics of materials, machine elements and solid mechanics). Project description This project aims to evaluate a new forged nickel-based superalloy, ATI 273TM, which offers high manufacturability and exceptional properties that outperform 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 aerospace component manufacturing processes while maintaining structural integrity and performance throughout its life cycle. The main users of the research results will be aerospace engineers and manufacturers, who can exploit the findings to design more reliable and efficient aircraft engines, reducing operating costs and environmental impact. Duties and responsibilities 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 extensive thermodynamic characterizations and optimization of heat treatments. Your tasks will include conducting experimental studies to optimize heat treatment processes as well as performing detailed microstructure analysis 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 applicability in aerospace 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 and at national and international conferences. You will take both compulsory and elective 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 the experimental and theoretical aspects of scientific work, which will foster your development as a researcher. Qualifications We are looking for an exceptional candidate who combines deep theoretical knowledge with a strong interest in experimental research. This PhD position focuses on material characterizations and thermodynamic calculations, essential elements of our pioneering research project. The ideal candidate will hold a Master's degree in Materials Engineering, Metallurgy, Mechanical Engineering or equivalent field, and demonstrate a strong foundation in the principles of materials science. We value candidates who are not only motivated and enthusiastic but also capable of conducting cutting-edge research, working independently and contributing effectively as part of a dynamic team. Excellent communication skills and fluency in both spoken and written English are essential. During the evaluation, particular attention will be paid to: - Knowledge and experience directly relevant to the research project in question. - the quality of the thesis or other relevant scientific publications - communication and collaboration skills - Personal qualities that promote productivity in research work. This PhD position offers the opportunity to participate in cutting-edge research on space materials at the forefront of the field, within a collaborative and supportive environment.
