摘要：

The influence of sulphidation on the metallic phase in a series of Fe100-xCrx alloys (x less than or equal to 15) was investigated by means of Fe-57 Mossbauer spectroscopy. The results obtained gave evidence that the sulphidation at 1073 K is selective in the atmosphere of H-2/H2S, with the partial pressure of sulphur ranging from 10(-7) to 10(-9) atm. At x(cr) = 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.
