WebOct 11, 2024 · Pearlite is a mixture composed of eutectoid ferrite and eutectoid cementite. It is one of the compositional phases of microscopic structure of steel, and the product of eutectoid transformation. It is usually represented by the symbol P. It is named so because its microscopic image looks like mother-of-pearl. 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.

Austenite only forms when an iron-based alloy is heated above about 750°C (1382°F) but not above about 1450°C (2642°F). Austenite keeps its form at room temperature when special alloying elements have been added to the iron-based alloy. iphlopWebMar 4, 2024 · Pearlite is a mechanical mixture composed of ferrite and cementite, which is formed by eutectoid transformation of austenite.
