Transmission electron microscopy of high pressure metal dusted 316 stainless steel

Comparative Study of the Growth of CNTs On Stainless Steel With and Without the External Catalyst

“…While these reflections are weak in DG sample and are most likely stemming from the carburization of SS in contact with ethylene at elevated temperature, carbide peaks of CG sample, clearly Fe 3 C, are strong and explicit. Concerning the nature of carbides observed in DG sample and their role in CNT growth, similarities can be found in the literature of dusting corrosion of SS (38)(39)(40), in terms of the coexistence of iron and chromium carbides, and partial presence of Cr 2 FeO 4 .…”
