Viktiga resultat som projektet gav

The purpose of this project was to identify synchrotron- and neutron techniques for quantitative characterization of nitrocarburized powertrain components. This is vital to improve nitrocarburizing process control and tailoring to specific steel grades in the manufacturing of transmission and engine components. The project group concludes that the project objective is met, since 2D-XRD mapping in combination with nanoindentation is suggested for a pilot study.

Långsiktiga effekter som förväntas

The project has identified synchrotron 2D-XRD mapping as the most promising synchrotron technique to quantitatively characterize nitrocarburized powertrain components. We will pursue a proof-of-concept by applying for beamtime on nanoMAX at MAX IV. This beamline allows for time-resolved quantitative characterization in combination with mechanical testing using nanoindentation. Results of such pilot study will show how mechanical properties relates to generated microstructure by material and processing.

Upplägg och genomförande

The project was conducted by Volvo Trucks in collaboration with RISE. We have reported on LSRI-techniques that can be used to characterize properties/features of nitrocarburized powertrain-components. The project has considered tomography- and spectroscopy techniques, although concluded that diffraction techniques should be a priority. 2D-XRD mapping, for instance at nanoMAX (MAX IV), obtains a diffraction pattern from which the phase structure, lattice constant, and strain distribution can be analyzed and visualized.
