Purpose and goal
Stronger steel lowers structural mass, increases payload and decreases environmental impact. Increased stresses, however, makes the material more sensitive to micro particle impurities and therefore increase demand on corresponding detection technique. Today, slow 2D microscope based techniques are used. The X-ray sources at the new synchrotron facilities gives X-rays of such intensity and quality so that 3D tomography images with relevant resolution can be made within reasonable time. The target is to verify this method with the industrial process development.
Expected results and effects
A better method compared to present for the detection and quantification inclusions in steel. The method should be possible to implement by the steel companies in their quest of development of better products for the manufacturing industry.
Planned approach and implementation
One steel producer, SSAB, and two research institutes, Swerim and Rise, take part in the project. Highly resolved 3-dimensional imaging of some different materials will be recorded using synchrotron light at DESY and evaluated with respect of steel inclusions. Results will be compared with data from conventional testing.
