Examples
-
However, upon cooling this steel, the carbon again enters into combination with a definite proportion of iron (the carbide "cementite," Fe3C), and accumulates into small crystals which can be seen under a good microscope.
The Working of Steel Annealing, Heat Treating and Hardening of Carbon and Alloy Steel 1916
-
The carbon absorbed by the iron does not take on a graphitic form, however, as in the case of cast iron, but enters into a chemical compound with the iron, a hard brittle substance called "cementite" by metallurgists.
The Working of Steel Annealing, Heat Treating and Hardening of Carbon and Alloy Steel 1916
-
The ferrite _i. e._, the iron is increased in strength by the resistance offered by the cementite which is the simple iron-carbon combination known to metallurgists as Fe3C.

-
When cooled slowly below 670 degrees, martensite yields a heterogeneous mixture of pearlite and ferrite (or cementite, if the original mixture contained between 0.8 per cent. and two per cent. of carbon).

-
Higher carbon steels show films of cementite outlining grains of pearlite (Fig. 48).

Martensite is usually considered to be a solid solution of cementite in beta iron.

At that moment, in fact, the ferrite, cementite or pearlite which previously existed has lost its identity by everything going into the solid solution called austenite.

One of these is pure iron, and the other is pure cementite.
