The material is hyper eutectoid and the room temperature microstructure shown has regions of primary cementite (white) and pearlite (aFe + Fe3C) crystallites FE3C · Vegetation.

The potential reproduces, for example, the lattice parameter(s), formation energies and elastic properties of the principal Fe and Cr carbides (Fe3C, Fe5C2, Fe7C3, Cr3C2, Cr7C3, Cr23C6), the Fe–Cr mixing energy curve, formation energies of simple C point defects in Fe and Cr, and the martensite lattice anisotropy, with fair to excellent agreement with empirical results. Cementit ili željezov karbid (Fe 3 C) je vrlo tvrd i krt kemijski spoj, sastojina je tehničkog željeza koja uzrokuje njegovu tvrdoću.To je metastabilan intersticijski spoj (ugljik se otapa u čvrstom željezu jer su njegovi atomi puno manji), koji sadrži 6,67% ugljika (masenih udjela).

A series of designed experiments disclosed that (1) N-doped carbon substrate, Fe/Fe3C nanocrystals or Fe–Nx themselves did not deliver the high activity; (2) the catalysts with both Fe/Fe3C nanocrystals and Fe–Nx exhibited the high activity; (3) the higher content of Fe–Nx gave the higher activity; (4) the removal of Fe/Fe3C nanocrystals severely degraded the activity; (5) the blocking of Fe–Nx downgraded the activity and the recovery of the blocked Fe–Nx recovered the activity.
