At Ovako in Hofors, this master thesis is your chance to dive deep into the microscopic world of steel – and explore how tiny structural differences can lead to major performance gains. Your mission? To investigate how different heat treatments and alloy compositions influence low-temperature creep behaviour – a key factor in ensuring long-term dimensional stability in critical components.

A thesis for those who want to connect structure to performance

Fasteners, joints, and other components often rely on maintaining their shape and strength under constant load. But even small, slow deformations – like creep – can compromise that integrity over time. In this thesis, you'll study how specific microstructures, such as pearlite, martensite and bainite, affect the creep resistance of steel at lower temperatures.

Through material testing and detailed microstructural analysis, you’ll explore the relationships between alloying, heat treatment and time-dependent deformation. Your work will help identify which structures perform best – and why – so we can better tailor our materials to meet future engineering challenges.

You’ll be based in Hofors, Sweden, with the possibility of spending time in Japan. Working closely with researchers at Ovako Group R&D, you’ll be part of a team where scientific insight and industrial relevance go hand in hand.

Why choose Ovako?

If you're fascinated by how steel behaves at the microscopic level – and want to translate that knowledge into real-world improvements – this is the project for you. At Ovako, you’ll find a research-driven environment where curiosity is encouraged, knowledge is shared, and your contribution truly matters.

And you’ll do it all in a workplace where people, materials and sustainability are in constant focus – a pretty great combo, if you ask us.

Is this you?

To thrive in this thesis, we think you are curious, structured and motivated by understanding the science behind performance. You might be in the final stages of your studies in materials science, metallurgy or mechanical engineering – ideally with a focus on heat treatment, microstructure or creep behaviour.

Experience with metallographic analysis, microstructure quantification and material testing is a plus. Fluency in English, both written and spoken, is expected – as is an interest in applied research with global relevance.
