Purpose and goal

The aim of the project was to develop a method for analyzing inclusions in steel based on tomography with synchrotron light that can exceed conventional methods in terms of time requirements and quality. The goal was to develop a way of working for the method and to evaluate the speed and quality of the new method in comparison with existing methods.

Expected results and effects

The set goals for the project were achieved. Measurements done with the new method are faster compared to existing methods. We could also ensure the reliability in comparison to standard lab methods. The expected effect is that SSAB will use the new knowledge regarding the performance of this new method to find new measurable cleanliness parameters that can be utilized to improve the SSAB production process and Products.

Planned approach and implementation

Materials were supplied by SSAB and the samples were prepared at Swerim AB in Kista. Tomography measurements were done at the synchrotron Petra III in Hamburg in parallel with measurements using standard microscopy based methods done at SSABs R&D department in Oxelösund, followed by analysis and comparison of results using the different methods. The work has been presented both at external seminars and internally at the different project partners. A manuscript for publication in a peer-review journal is the making.

The project description has been provided by the project members themselves and the text has not been looked at by our editors.
