Influence of surface treatment on microstructure of stainless steels studied by Mossbauer spectrometry
2019
Abstrakt
Examination of surface microstructure of stainless steels is presented. Transmission Mossbauer spectrometry and Conversion Electron Mossbauer Spectrometry which provide information from the bulk and surface regions, respectively, were used.
We concentrate on structural modifications that were caused by surface treatments including grinding, polishing, and electrolytic etching. Scanning Electron Microscopy with Energy Dispersive Spectrometry was adopted for visualization of surface differences.
Formation of magnetic phases was revealed in the surface regions of X6CrNiTi1810 steel while no substantial effect of surface treatment was found in the ATABOR steel. Bulk regions in both steels are not affected by surface treatment.
