The proportion of ferrite and cementite forming above the eutectoid point can be calculated from the iron / iron carbide equilibrium phase diagram using the lever rule.
22.
The eutectic mixture of austenite and cementite is 4.3 % carbon, Fe 3 C : 2Fe, with a melting point of 1147 �C.
23.
Tungsten slows the formation of cementite, keeping carbon in the iron matrix and allowing martensite to preferentially form at slower quench rates, resulting in high speed steel.
24.
Upon cooling slowly, the solution of iron and carbon, ( a single phase called austenite ), will separate into platelets of the phases ferrite and cementite.
25.
The rate at which the steel is cooled through the eutectoid temperature ( about 727�C ) affects the rate at which carbon diffuses out of austenite and forms cementite.
26.
The eutectoid composition of austenite is approximately 0.76 % carbon; steel with less carbon content ( hypereutectoid steels ) will form cementite before reaching the eutectoid point.
27.
If tempered at higher temperatures, between and, or for longer amounts of time, the martensite may become fully ferritic and the cementite may become coarser or spheroidize.
28.
The end product below 0.8 % carbon content is a pearlite-ferrite mixture, and that above 0.8 % carbon content is a pearlite-cementite mixture.
29.
Elemental silicon is added to molten cast iron as ferrosilicon or silicocalcium alloys to improve performance in casting thin sections and to prevent the formation of cementite where exposed to outside air.
30.
A team of researchers based at the Technical University of Dresden that uses X-rays and electron microscopy to examine Damascus steel discovered the presence of cementite nanowires and carbon nanotubes.
