Examples

Cooling a mixture of iron with 0.8% carbon slowly below 723 °C to room temperature results in separate, alternating layers of cementite and ferrite, which is soft and malleable and is called pearlite for its appearance. Source: Internet

For steels that have less than 0.8% carbon (hypoeutectoid), ferrite will first form until the remaining composition is 0.8% at which point the pearlite structure will form. Source: Internet

In a hypereutectoid composition (greater than 0.8% carbon), the carbon will first precipitate out as large inclusions of cementite at the austenite grain boundaries and then when the composition left behind is eutectoid, the pearlite structure forms. Source: Internet

The steel can then be tempered by reheating to a temperature in between, changing the proportions of pearlite and martensite. Source: Internet

The thickly coated back cools more slowly retaining the pearlite steel characteristics of relative softness and flexibility. Source: Internet
