Abstract
Mössbauer spectrometry is a nuclear-based analytical method with a huge diagnostic potential. The energetic resolution of the Mössbauer effect techniques is about five orders of magnitude better than that of atomic spectra.
In this work, we elucidate structural features of advanced corrosion resistant LC 200 N steel. Elevated Cr and N content provide high hardness and wear resistance of this perspective material which can be considered for possible applications in nuclear installations.
In order to understand structural arrangement and the role of the alloying elements, for the analysis we have employed several additional characterization techniques as scanning electron microscopy, micro X-ray fluorescence, and neutron activation analysis. Samples were investigated both in the as-prepared state, i.e. after electro-erosive cutting from original ingots as well as after surface polishing.
Surface contamination by the products of cutting was unveiled and presence of additional elements such as Zn, Cu, and As is observed. They do not belong to the alloy constituent elements but result from the cutting process.
After surface polishing, only the original composition of the alloy is observed.
