Examples include calcium carbide (CaC 2 ), silicon carbide (SiC), tungsten carbide (WC) (often called simply carbide when referring to machine tooling), and cementite (Fe 3 C), citation each used in key industrial applications. Source: Internet
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
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
No large inclusions of cementite will form at the boundaries. Source: Internet
When carbon moves out of solution with iron it forms a very hard, but brittle material called cementite (Fe 3 C). Source: Internet
