WebApr 5, 2024 · One of the key components is a microstructure known as pearlite. Pearlite is formed when austenite, the high-temperature phase of iron, undergoes a eutectoid reaction with carbon during cooling. This process results in a layered structure consisting of alternating layers of ferrite and cementite. WebPremier Tech’s peat moss comes from bogs that are certified under the Veriflora Program.

It is harder than either pure iron or pure carbon, but not as hard as steel. Pearlite is formed during the cooling of austenitic steels and cast irons. It is also found in some hypereutectoid steels.

WebPearlite is a two-phase structure, consisting of alternate plates of ferrite and cementite. The active nucleus is defined as the first one of ferrite, or cementite, to form with a lattice orientation with austenite, which will later be found in the transformed products. WebPearlite is formed during sufficiently slow cooling in an iron-carbon system at the eutectoid point in the Fe-C phase diagram (723 °C, eutectoid temperature). In a pure Fe-C alloy it contains about 88 vol.% ferrite and 12 vol.% cementite. Pearlite is known for being tough and, when highly deformed, extremely strong.
