What is Cementite?

Cementite or Iron Carbid contain iron, carbon, and, more specifically, an intermediate metal caride with the molecular arrangement Fe3C. Its weight is 6.67%, 9.3%. It has a relative density of 7.694, and is gray-white in color. You can dissolve it in water, or dilute acid. Avoid reactivity in dry environments. Oxidizing with moist oxygen can create iron oxide and carbon. This mineral is known for its orthorhombic crystal form. It’s hard and delicate, so it is often classified as ceramic. It’s essential in black metalurgisty when it is at its most pure form.

Fe3C: What does stand for?

Iron carbide Fe3C can also be called cementite.

How is cementite formed?

Primary cementite:

The iron-carbon alloy mixture crystallizes in equilibrium and cementite develops. This is the hypereutectic mixture (hypereutectic iron) and it’s then cooled down to below its liquidus temperatures.

Eutectic Cemented Cementite:

Ledeburite structures feature a narrow strip of cementite which is uniformly distributed within an austenite matrix.

The preeutectoid-cementite phase of

Alloys of hypoeutectoid-hypereutectoid composition are always precipitated when the temperature drops. The same is true for proeutectoid stages such as the proeutectoid iron, hypoeutectoid Iron and proeutectoid cementedite. This is hypereutectoid Metal. Due to the different conditions that are required for formation, proeutectoid phases can be separated into Widmanstatten (block), and reticulate.

Eutectoid cementite:

Eutectoid, the name for cementite which is found in pearlite.

Secondary cementite

The carbon content of austenite can be reached saturation if iron-carbon alloys such as hypoeutectic ferrous cast iron, hypereutectic ferrous cast iron, and hypoeutectic fer cast iron are slow cool. This cementite is formed along the austenite grain boundary with an underlying microstructure network. You can also call the secondary cementite which is formed in austenite by precipitating iron-carbon alloy.

Tertiary cementedite:

When the iron’s equilibrium temperature drops below the PQ line in the carbon-iron solution in industry, it is known as saturation. This means that the ferrite will not sorb water and the temperature will reach saturation. It then drops back to normal. The tertiary carbonite, due to its very low amount, is precipitated at the ferrite grains boundary. It usually occurs along the boundary only intermittently.

These are the ones that exist beyond the mechanical mixture.
