During slow cooling of an iron-carbon alloy, pearlite forms by a <a href="/wiki/Eutectoid" class="mw-redirect" title="Eutectoid">eutectoid</a> reaction as <a href="/wiki/Austenite" title="Austenite">austenite</a> cools below 723 °C (1,333 °F) (the eutectoid temperature).

Likewise steels with higher carbon content (<a href="/wiki/Heat_treating#Hypereutectoid_alloys" title="Heat treating">hypereutectoid steels</a>) will form cementite before reaching the eutectoid point. The proportion of ferrite and cementite forming above the eutectoid point can be calculated from the iron/iron—carbide equilibrium phase diagram using the <a href="/wiki/Lever_rule" title="Lever rule">lever rule</a>. </p><p>Steels with pearlitic (eutectoid composition) or near-pearlitic microstructure (near-eutectoid composition) can be drawn into thin wires. Such wires, often bundled into ropes, are commercially used as piano wires, ropes for suspension bridges, and as steel cord for tire reinforcement. High degrees of wire drawing (logarithmic strain above 3) leads to pearlitic wires with yield strengths of several gigapascals. It makes pearlite one of the strongest structural bulk materials on earth.<sup id="cite_ref-strong_1-0" class="reference"><a href="#cite_note-strong-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> Some hypereutectoid pearlitic steel wires, when cold wire drawn to true (logarithmic) strains above 5, can even show a maximal tensile strength above 6 GPa (870 ksi).<sup id="cite_ref-strong2_2-0" class="reference"><a href="#cite_note-strong2-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup> Although pearlite is used in many engineering applications, the origin of its extreme strength is not well understood. It has been recently shown that cold wire drawing not only strengthens pearlite by refining the lamellae structure, but also simultaneously causes partial chemical decomposition of cementite, associated with an increased carbon content of the ferrite phase, deformation induced lattice defects in ferrite lamellae,<sup id="cite_ref-3" class="reference"><a href="#cite_note-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup> and even a structural transition from crystalline to amorphous cementite. The deformation-induced decomposition and microstructural change of cementite is closely related to several other phenomena such as a strong redistribution of carbon and other alloy elements like <a href="/wiki/Silicon" title="Silicon">silicon</a> and <a href="/wiki/Manganese" title="Manganese">manganese</a> in both the cementite and the ferrite phase; a variation of the deformation accommodation at the phase interfaces due to a change in the carbon concentration gradient at the interfaces; and mechanical alloying.<sup id="cite_ref-strongpearlite_4-0" class="reference"><a href="#cite_note-strongpearlite-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup> </p><p>Pearlite was first identified by <a href="/wiki/Henry_Clifton_Sorby" title="Henry Clifton Sorby">Henry Clifton Sorby</a> and initially named sorbite, however the similarity of microstructure to <a href="/wiki/Mother_of_pearl" class="mw-redirect" title="Mother of pearl">nacre</a> and especially the optical effect caused by the scale of the structure made the alternative name more popular. </p><p>Pearlite forms as a result of the cooperative growth of ferrite and cementite during the decomposition of austenite. The morphology of pearlite is significantly affected by the cooling rate and coiling temperature. At lower coiling temperatures, pearlite forms with finer lamellar spacing, resulting in enhanced mechanical properties due to the finer distribution of ferrite and cementite layers. Conversely, at higher coiling temperatures, pearlite forms with coarser lamellae, and a smaller amount of pearlite is observed as coarse cementite particles tend to dominate the structure. The carbon diffusion during the formation of pearlite, just ahead of the growth front, is critical in determining the thickness of the lamellae and, consequently, the strength of the steel.<sup id="cite_ref-Alvarengahd_5-0" class="reference"><a href="#cite_note-Alvarengahd-5"><span class="cite-bracket">[</span>5<span class="cite-bracket">]</span></a></sup> </p><p><a href="/wiki/Bainite" title="Bainite">Bainite</a> is a similar structure with lamellae much smaller than the <a href="/wiki/Wavelength" title="Wavelength">wavelength</a> of <a href="/wiki/Visible_light" class="mw-redirect" title="Visible light">visible light</a> and thus lacks this pearlescent appearance. It is prepared by more rapid cooling. Unlike pearlite, whose formation involves the diffusion of all atoms, bainite grows by a displacive transformation mechanism. </p><p>The transformation of pearlite to austenite takes place at lower critical temperature of 723 °C (1,333 °F). At this temperature pearlite changes to austenite because of nucleation process. </p> <div class="mw-heading mw-heading2"><h2 id="Eutectoid_steel">Eutectoid steel</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Pearlite&action=edit&section=2" title="Edit section: Eutectoid steel"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Eutectoid steel can in principle be transformed completely into pearlite; hypoeutectoid steels can also be completely pearlitic if transformed at a temperature below the normal eutectoid.<sup id="cite_ref-Alvarenga_6-0" class="reference"><a href="#cite_note-Alvarenga-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-7" class="reference"><a href="#cite_note-7"><span class="cite-bracket">[</span>7<span class="cite-bracket">]</span></a></sup> Pearlite can be hard and strong but is not particularly <a href="/wiki/Toughness" title="Toughness">tough</a>.
