Iron carbon diagram
Iron-Carbon Phase Diagram with Detailed Explanation: If the percentage of the carbon is in the range of 0 to 2.11 % then it is called Steel and if the percentage of carbon is in the range of 2.11 to 6.67% then it is called Cast iron. As the carbon content increases, it produces more Iron-Carbide volume and that phase will exhibit high hardness. The iron-carbon diagram provides a valuable foundation on which to build knowledge of both plain carbon and alloy steels in their immense variety. Fig. 1. The iron-carbon diagram. It should first be pointed out that the normal equilibrium diagram really represents the metastable equilibrium between iron and iron carbide (cementite). Iron-Carbon Diagram The iron-carbon diagram was developed to show the microstructural condition of metal as a function of temperature (y axis) and carbon content (x axis). In the partial diagram shown here, we only consider the range of steel with a carbon content of up to a maximum of 2%.

Article shared by : ADVERTISEMENTS: In Fe-Fe3C diagram, three important invariant (at a constant temperature) reactions take place as described below: 1. Peritectic Reaction: A peritectic reaction, in general, can be represented by an equation: where, L represents a liquid of fixed composition ... The Iron Carbon Phase Diagram There is more to the iron-carbon phase diagram than related in the backbone. In particular, there is some nomenclature that I avoided in the main text but that is important for understanding other writings about iron and steel. So let's start with a phase diagram that contains maximal information: Iron-carbon phase diagram Dr. Dmitri KopeliovichIron-carbon phase diagram describes the iron-carbon system of alloyscontaining up to 6.67% of carbon, discloses the phasescompositions and their transformations occurring with the alloys during their cooling or heating. Carboncontent 6.67% corresponds to the fixed composition of the iron carbide Fe3C. Conventionally, the complete Fe-C diagram should extend from 100% Fe to 100% carbon, but it is normally studied up to around 6.67% carbon as is also illustrated in Fig. 1.22, because iron alloys of practical industrial importance contain not more than 5% carbon. Thus, this diagram is only just a part of the complete Fe-C equilibrium diagram.
Iron Carbon Phase Diagram At the low-carbon end of the metastable Fe-C phase diagram, we distinguish ferrite (alpha-iron), which can at most dissolve 0.028 wt. % C at 738 °C, and austenite (gamma-iron), which can dissolve 2.08 wt. % C at 1154 °C. Iron carbon phase diagram ferrite This solution has a melting point of 1538°C. Ferrite is the softest structure on the iron-iron carbide diagram. Ferrite acts magnetically at low temperatures, but its magnetic properties are dethatched once its temperature rises and above 786°C temperature it becomes non-magnetic. The iron-iron carbide (Fe-Fe 3 C) phase diagram. The percentage of carbon present and the temperature define the phase of the iron carbon alloy and therefore its physical characteristics and mechanical properties. The percentage of carbon determines the type of the ferrous alloy: iron, steel or cast iron. Manufacturing Engineering Multiple Choice Questions on "Iron Carbon Phase Diagram-1". 1.

The iron-carbon diagram provides a valuable foundation on which to build knowledge of both plain carbon and alloy steels in their immense variety. A study of the constitution and structure of all steels and irons must first start with the iron-carbon equilibrium diagram. Many of the basic features of this system (Fig. 1) influence the behavior ... Interactive Iron-Carbon phase diagram. Gives information on Carbon content, temperature and phases of any point on the diagram. The Iron-Iron Carbide (Fe-Fe3C) Phase Diagram In their simplest form, steels are alloys of Iron (Fe) and Carbon (C). The Fe-C phase diagram is a fairly complex one, but we will only consider the steel part of the diagram, up to around 7% Carbon.

According to the Iron-Carbon phase diagram, we call the c omposition of steel that contains 0.8 percent of carbon as eutectoid composition. It is a certain composition where, upon cooling austenite to lower than 723°C (eutectoid reaction), the austenite turns into pearlite (alternate layers of ferrite and cementite).
The Iron carbon equilibrium diagram (also called the iron carbon phase diagram) is a graphic representation of the respective microstructure states of the alloy iron - carbon (Fe-C) depending on temperature and carbon content. The iron carbon phase diagram is commonly used to fully understand the various phases of steel and cast iron.
Phase diagrams are graphical representations of the phases present in an alloy at different conditions of temperature, pressure, or chemical composition. Phase Diagram of Iron-carbon System The simplest ferrous alloys are known as steels and they consist of iron (Fe) alloyed with carbon (C) (about 0.1% to 1%, depending on type).
