Two Doctoral researchers in the field of microstructural design of advanced high-strength steels for enhanced fatigue resistance - Hiring in process/Finished, not possible to apply

We are now looking for two highly motivated

Doctoral researchers

in the field of microstructural design of advanced high-strength steels for enhanced fatigue resistance to join the Materials and Mechanical Engineering Research Unit for an exciting project funded by the Kvantum Institute.

About us

MME is aiming to be a world-leading research unit in the field of physical metallurgy of high-strength steels, with a focus on improving the efficiency and sustainability of modern machines, vehicles, and structures. We strive to provide innovative solutions to complex engineering challenges, and to contribute to the development of modern structure and mobile machinery that are both environment-friendly as well as cost-effective.

About the job

The project focuses on the development of sustainable ultrahigh strength steels with exceptional fatigue resistance using cutting-edge processing techniques. The research aims to design complex, multiphase steels thorough microstructural engineering that will impart superior mechanical properties in respect of strength, ductility, and toughness, as well as improved fatigue and hydrogen embrittlement resistance.

The selected candidates will undergo extensive training in the characterization of multi-scale advanced materials and failure micro-mechanisms. This position offers a unique opportunity to interact with the academics and researchers of various research groups at the MME research unit in order to implement research goals. As part of the core team, you will investigate the complex microstructures of multiphase steels at different length scales down to atomic scale, and study their mechanical response to uniaxial and cyclic loading conditions, clarifying related deformation and fracture mechanisms. Your training will involve using advanced characterization methods (3D-Atom Probe Tomography, in-situ synchrotron-based high-energy X-ray diffraction, Transmission Electron Microscopy, in-situ Scanning Electron Microscopy, etc.), and mechanical property characterization techniques (low/high cycle fatigue, fatigue crack growth, etc.).

In addition, you will gain experience in conducting physical simulation experiments using state-of-the art facilities, CALPHAD-based thermodynamic and numerical modeling, which will allow to explore and correlate the structure-property relationships. This position is ideal for someone eager to advance their skills through cutting-edge research, while contributing to the development of sustainable, high-performance materials for the future.

Responsibilities

• Conducting original research to develop innovative steel compositions and processing methods aimed at enhancing fatigue resistance.
• Applying different modeling techniques to simulate microstructural evolution and predict the effect of processing parameters on material properties.
• Development of new modelling solutions to predict the fatigue resistance of ultrahigh strength steels.
• Collaborate with interdisciplinary teams of researchers and engineers to design and execute experimental studies to validate modeling predictions.
• Analyze experimental data to gain insights into the mechanisms governing hydrogen embrittlement resistance.
• 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.

Requirements for the position

• A master's degree in a relevant field that was awarded not more than five years ago.
• A transdisciplinary research orientation with demonstrated research experience or interest.
• Capacity to collaborate in research and research dissemination activities.
• Excellent written and interpersonal communication skills in English.
• Strong analytical and problem-solving skills.
• Ability to work independently and collaboratively in a team environment.
• Motivated and self-driven with a passion for scientific research and innovation.
