WebJun 30, 2024 · The cooling curve of pure iron (Fe) has a series of thermal arrests at which different processes take place in the microstructure. The first thermal arrest is at the solidification temperature of 1536 °C. At this point the melt crystallizes in a body-centered cubic lattice structure (bcc). In this state the iron is also called \(\delta\)-iron ... WebFigure 7. Cooling rate that permits both pearlite and martensite formation. Sometimes the cooling curve may pass through the middle of the Austenite-Pearlite transformation zone. In Figure 7, cooling curve E indicates a cooling rate which is not high enough to produce 100% martensite. This can be observed easily by looking at the TTT diagram. WebC. Cooling Curves and Phase Diagrams. All pure crystalline solids, including metals, have the property of melting and freezing at a single temperature. If a pure metal is melted and allowed to cool slowly, its cooling curve, i.e. temperature vs. time behavior will resemble those labeled A and D in Fig. 3. electric scooter wagon
