1
Light Microscopy of Carbon Steels
Cementite This term was first applied by Professor Howe to carbide of iron in the
separate state as a constituent of steel. The researches of Abel, Arnold, Miiller,
Osmond and others show it to have the formula Fe3C. The term may be, however
, ...

Steel Metallurgy for the Non-metallurgist
line between pure pearlite at 0.77% C and pure cementite at 6.7% C. The formula
now becomes: Fraction cementite (X Fig. 4.8 Hypereutectoid 1095 steel air
cooled from 850 °C (1560 °F) to room temperature, with dark austenite grains ...
3
Failure Analysis of Heat Treated Steel Components
Pearlite will form if the carbon content in the austenite is 40.83%, and excess
carbon will form cementite. Excess cementite (proeutectoid cementite) will
deposit in the grain boundaries. Because cementite (Fe3C) contains a specific
amount ...
4
Physical Metallurgy for Engineers
However, this cementite does not appear in the microstructure as an independent
phase. It contributes only to the thickening of cementite plates within the
ledeburite.) At the temperature T=Ts, the Xs-solid solution corresponding to
composition ...
5
High-Temperature Corrosion and Materials Applications
This condition promotes the formation of cementite (Fe3C) on the metal surface.
As shown in Fig. 5.1, the calculated carbon activities in equilibrium with cementite
are higher than 1.0 at 700 °C (1292 °F) and lower temperatures. Figure 5.56 ...
6
Principles of heat treatment of steels
Furthermore, more often than not, the carbide precipitating in bainitic ferrite is e-
carbide rather than cementite. The overall kinetics of this stage of tempering may
also be followed by measuring the changes in length of a specimen, as austenite
...
7
Steel Heat Treatment: Metallurgy and Technologies
2.4.1.4 Third Stage of Tempering In the temperature range of 250 to 7508C,
cementite precipitates within the martensite. The composition of the cementite is
Fe3C. In alloyed steels, it is referred as M3C, where M corresponds to
substitutional ...
8
Analytical Characterization of Aluminum, Steel, and Superalloys
The delta ferrite forms in the last regions to solidify and has an interconnected
dendritic appearance. 3.4.4 Graphite and Cementite Carbon in iron exists as
graphite, cementite, or alloy carbides. There is almost no solubility for carbon in
ferrite.
D. Scott MacKenzie, George E. Totten, 2005
9
Understanding Solids: The Science of Materials
Ultimately the austenite transforms into a two-phase mixture of ferrite (oi-ferrite)
and cementite (Fe3C) at a temperature of 727 °C (T2, Figure 8.29a), with internal
strain likely to provide the driving force. The transformation is complex.
Richard J. D. Tilley, 2013

Metallographer's Guide: Practice and Procedures for Irons ...
One set represents the iron-cementite (Fe3C) phase diagram (solid lines), and
the other set represents the iron-graphite phase diagram (dashed lines). The
reason that there are two sets of phase boundaries is that the stable (equilibrium)
