Description

The influence of sulphidation on the metallic phase in a series of Fe100-xCrx alloys (x ≤ 15) was investigated by means of 57Fe Moessbauer spectroscopy. The results obtained gave evidence that the sulphidation at 1073 K is selective in the atmosphere of H2/H2S, with the partial pressure of sulphur ranging from 10-7 to 10-9 atm. At xcr 5.0(1) at.%, a change of the sulphidation preference occurs. For x < 5.0 at.%, the sulphidation results in an enrichment of the metallic phase in chromium, while for x > 5.0 at.%, in iron.
