- Cementite - Wikipedia
Cementite (or iron carbide) is a compound of iron and carbon, more precisely an intermediate transition metal carbide with the formula Fe 3 C By weight, it is 6 67% carbon and 93 3% iron
- What is Ferrite, Cementite, Pearlite , Martensite, Austenite
2 Cementite: This is a definite carbide of iron (Fe3C) which is extremely hard, being harder than ordinary hardened steel or glass Cementite increases generally with the proportion of carbon present, and the hardness and also the brittleness of cast iron is believed to be due to this substance
- What is Cementite - Fe3C - Definition | Material Properties
Cementite (Fe3C) is a metastable compound, and under some circumstances it can be made to dissociate or decompose to form α-ferrite and graphite, according to the reaction: Fe 3 C → 3Fe (α) + C (graphite)
- Cementite | Metallurgy for Dummies
Cementite is a chemical compound whose inclusion hardens steel Each molecule is made of three iron atoms bonded to one carbon atom (Fe3C) to form a crystal lattice structure called orthorhombic, where multiple rectangular prisms arise from the same base structure and intersect at 90 degree angles
- Cementite - an overview | ScienceDirect Topics
Cementite is a hard, brittle compound with an orthorhombic crystal structure having the composition Fe3 C (Fig 11 4) Upon slow cooling from the austenite phase, cementite and ferrite form as parallel plates into a two-phase microstructure called pearlite
- Cementite – Metallurgy

- Cementite in Steel Microstructure: Formation, Properties Impact . . .
Cementite, also known as iron carbide (Fe₃C), is a hard, brittle intermetallic compound that forms within steel microstructures It is characterized by a specific stoichiometric ratio of three iron atoms to one carbon atom, resulting in a distinct phase with unique properties
- Cementite: Harnessing the Power, 4 Properties Applications
Cementite is a metallic ferromagnet at room temperature, exhibiting paramagnetic behavior beyond the Curie temperature The Curie temperature has been reported to be around 186°C, with varying claims ranging from 180°C to 240°C
