We are now looking for a

Two Doctoral Researchers

to join us in the Materials and Mechanical Engineering Research Unit, University of Oulu.

Position is fixed-term for 3,5 years, and focuses on the project NewGenH2Steel.

About us

Materials and Mechanical Engineering Research Unit, University of Oulu, is a world-leading research unit in the field of physical and mechanical metallurgy of advanced high-strength steels, with a focus on improving the efficiency and sustainability of structures, vehicles, and modern machines. We strive to provide innovative solutions to complex engineering challenges and to contribute to the development of modern structures and mobile machinery that are both environmentally friendly and cost-effective.

About the job

The project aims to explore innovative high-risk/high-gain ideas to develop new-generation hydrogen-resistant steels. The Doctoral researchers will work on developing sustainable ultrahigh-strength steels with an exceptional property combination through novel science-based approaches. Project findings could have a notable impact on the deployment of green hydrogen infrastructure, as needed to achieve net-zero carbon ambitions.
The doctoral researcher will be integrated into the Steel Fatigue Research Group and will have the opportunity to interact on a daily basis with other doctoral and postdoctoral researchers working on various field/research topic with diverse expertise.

Selected candidates will receive comprehensive training in the characterization of advanced high-strength steels, including micromechanical property evaluation under static and cyclic loading conditions. They will also gain hands-on experience in physical simulation using state-of-the-art facilities, as well as CALPHAD-based thermodynamic and numerical modelling to investigate and correlate structure–property relationships. The position provides a unique opportunity to collaborate with various research groups at the University of Oulu and international partners in pursuing shared research objectives. Overall, this role is ideal for individuals seeking to deepen their expertise through innovative research aimed at developing sustainable, high-performance steels for a carbon-neutral society.

Responsibilities

• Conducting original research aimed at designing multiphase metastable structures through swift processing.
• Analyze experimental data to gain insights into the mechanisms governing hydrogen embrittlement resistance.
• Applying modeling techniques to simulate microstructural evolution and predict the effect of processing parameters on material properties.
• Collaborate with interdisciplinary teams of researchers and engineers to design and execute experimental studies to validate modeling predictions.
• Present research findings at conferences, publish scientific papers in peer-reviewed journals, and contribute to the dissemination of knowledge within the scientific community.
• Work closely with industry partners to ensure the relevance and applicability of research outcomes to real-world engineering challenges.
