Sandvik Materials Technology (SMT) is carrying out important research with world-class synchrotron techniques that will open new avenues for alloy development. The PhD research project lead by Josefin Eidhagen, Research Engineer at SMT, is carried out at the Royal Institute of Technology (KTH) in collaboration with Lund University and funded by Swedish Foundation for Strategic Research (SSF).

High demands are often placed on the corrosion properties of the alloys, which means that SMT need to be at the forefront of our research. The research project strives to map the mechanisms that control the corrosion properties of nickel base alloys, with the anticipation to find more detailed knowledge about its degradation.

- In our research, we have discovered that nickel alloys behave differently compared to other alloys when it comes to corrosion, and in this doctoral project, I get the opportunity to deep dive in to corrosion mechanisms, which is very interesting, says Josefin Eidhagen.

- Even though we know what happens in connection with the corrosion process, we have not yet mapped the mechanisms that control the course of events. We hope to be able to clarify this through this doctoral project, says Anna Delblanc, researcher and chemist at SMT.

The research project is featured in the magazine “Research of the future” (Framtidens Forskning) and described as a particularly interesting project, enabling to carry out fundamental research directly relevant for, and in collaboration with industry. Read the article in Swedish here:
