Iron - Wikipedia Low-pressure phase diagram of pure iron The first three forms are observed at ordinary pressures. As molten iron cools past its freezing point of 1538 °C, it crystallizes into its δ allotrope, which has a body-centered cubic (bcc) crystal structure . Phase Diagram - Industrial Metallurgists The phase diagram indicates that an iron-carbon alloy with 0.5% carbon held at 900 °C will consist of austenite, and that the same alloy held at 650 °C will consist of ferrite and cementite. Furthermore, the diagram indicates that as an alloy with 0.78% carbon is slow cooled from 900 °C, it will transform to ferrite and cementite at about ... Iron-Carbon Phases - Metallurgy for Dummies The Iron-Carbon Phase Diagram The iron-carbon phase diagram is essentially a map. The most important part is shown in Figure 5. More details are given in Figure 6. Any point in the field of the diagram represents a steel containing a particular carbon content at a particular temperature. Ternary Phase Diagrams - ASM International the temperatures at which the various phase changes occur. Single-Phase Boundary and Zero-Phase Fraction Lines. Two-dimen-sional (2-D) sections of any multicomponent phase diagram, whether it is an isotherm or an isopleth, can be read by focusing on two lines that refer to one particular phase.
