Master thesis: Understanding high-temperature deformation mechanisms in cemented carbide materials

Sandvik Coromant, Sweden, offers a thesis project in the area of cemented carbide materials, to be carried out at Chalmers University of Technology in Gothenburg.

Background and work description

Sandvik Coromant, a division within the Sandvik Group, is a world-leading manufacturer of cutting tools in cemented carbide for turning, milling, and drilling. During cutting applications, the material is deformed. However, the deformation mechanisms are not completely understood.

Usage of state-of-the-art equipment for material characterization has the potential to increase the understanding of the deformation mechanisms. Scanning electron microscopy (SEM), with assistance of electron backscatter diffraction (EBSD), is the most suitable technique to get information about grain size and morphology. Atom probe tomography (APT) will provide information about the microstructure at an atomic level.

The project will start with a literature review. The student will produce specimens for the advanced material characterization techniques. This is expected to primarily be carried out at Sandvik Coromant in Stockholm. Analysis through EBSD and APT will be performed at Chalmers University of Technology. Finally, the results will be documented and presented.

Student background

We are primarily looking for someone studying physics, chemistry, materials science, mechanical engineering or similar. You must have a genuine interest in experimental work and have good writing skills. We put value in experience in independent experimental work.

As the work primarily will be carried out at Chalmers University of Technology, the applicant is assumed to have an accommodation in the Gothenburg area arranged. Time will also be spent, primarily in the beginning of the project, at Sandvik Coromant in Västberga, Stockholm.

Duration

The thesis project lasts 20 weeks, starting January 16, 2023.
