8 Apr 2021 Study of the evolution of FeNxCy and Fe3C species in Fe/N/C catalysts during the oxygen reduction reaction in acid and alkaline electrolyte.

Cementite (Fe3C) is a typical phase in carbon steels1 and is formed by the eutectoid reaction: austenite −→ ferrite + Fe3C.2 Fe3C is a very hard phase and Figure 1 shows the equilibrium diagram for combinations of carbon in a solid solution of iron. The diagram shows iron and carbons combined to form Fe-Fe3C at 10 Mar 2020 Fe3C or cementite. Cementite is a metastable phase of this alloy with a fixed composition of Fe3C. It decomposes extremely slowly at room Jul 25, 2018 - ENGINEERING BLOG Uncategorized - dedicated for all engineering team arround the world. Figure 15:Crystal structure of cementite, Fe3C (space group Pnma). The carbon filled trigonal Fe6 prisms and one empty Fe6 octahedron are emphasized. The figure above shows a typical Fe-Fe3C phase diagram.
