WebTwo types of ADI heat treatments of spheroidal cast iron, one step and two steps were performed. Selection of the optimal heat treatment parameters was based on the analysis … WebSince the compositions of most cast irons are around the eutectic point of the iron-carbon system, the melting temperatures closely correlate, usually ranging from 1,150 to 1,200 °C (2,102 to 2,192 °F), which is about 300 °C (572 °F) lower than the melting point of pure iron.

WebIron-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. WebTTT diagrams for (a) eutectoid, (b) hypoeutectoid, and (c) hypereutectoid steels. (b) and (c) show ... Cementite is a metastable phase, and there exists a true equilibrium between iron and graphite. In cast irons (2–4 wt% C) graphite occurs extensively. Equilibrium phase in steel (0.03–1.5 wt% C) is much more difficult to obtain. ray huff auburn al

WebWhite Cast Iron. It is the iron that displays white fractured surface due to the presence of cementite. With a lower silicon content and faster cooling, the carbon in white cast iron precipitates out of the melt as the metastable phase cementite, Fe3C, rather than graphite. The cementite which precipitates from the melt forms as relatively ...
