The iron-carbon system (steel and cast iron) MSE 2090: Introduction to Materials Science Chapter 9, Phase Diagrams 2 Component - chemically recognizable species (Fe and C Iron-Cementite diagram is not a true equilibrium diagram, since equilibrium means no change of phase with time, however long it may be. Graphite is more stable form of carbon. Cementite is a metastable phase, which decomposes to graphite if given long periods of time. Graphitisation, however, rarely occurs in steels and may take years to form.

Fig 1 Iron carbon phase diagram. C is an interstitial impurity in Fe. It forms a solid solution with alpha, gamma and delta phases of iron. Maximum solubility of C in alpha iron is 0.025 % at 727 deg C. Body centred cubic (BCC) iron has relatively small interstitial positions. Simplified Iron-Carbon phase diagram austenite ↔ pearlite (mixture of ferrite & cementite) The Austenite to ferrite / cementite transformation in relation to Fe-C diagram. MICROSTRUCTURE OF AUSTENITE. MICROSTRUCTUREOF PEARLITE Photomicrographs of (a) coarse pearlite (b) fine pearlite. 3000X. How much carbon can be dissolved in a phase is something that the phase diagram tells you.: Dissolved means that the foreign atoms are sitting as individuals in the crystal (interstitial places for carbon in iron) in some random distribution. In other words: they are extrinsic point defects.Any point inside the blue area in the phase diagram above (the a-phase or ferrite phase) denotes an.

Iron/Carbon Phase Diagram Iron shows a eutectic with Carbon allowing for a lower melting alloy Body Centered Tetragonal. 6. 7. 8 Carbon content can be reduced by reaction with oxygen and stirring. 9. 10 Eutectoid Steel Pearlite. 11 Time-Temperature-Transformation Diagram. 12 Time-Temperature-Transformation Diagram The primary phase of low-carbon or mild steel and most cast irons at room temperature is ferromagnetic α-Fe. It has a hardness of approximately 80 Brinell. The maximum solubility is about 0.02 wt% at 727 °C (1,341 °F) and 0.001% carbon at 0 °C (32 °F). When it dissolves in iron, carbon atoms occupy interstitial "holes". Being about twice the diameter of the tetrahedral hole, the carbon. 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: A 1: The upper.

Iron Carbon Phase Diagram Edelstahl Harten

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.

Carbon is the most important alloying element in iron. For this reason, even the smallest changes in carbon content can have massive changes in the characteristics of the material. However, the importance of the iron-carbon phase diagram decreases rapidly if the material is rapidly cooled or heated. The diagram is also less meaningful if the proportion of other alloying elements increases.
