Iron alloy phase diagram
Below 912 °C (1,674 °F), iron has a body-centered cubic (bcc) crystal structure and is known as α-iron or ferrite. It is thermodynamically stable and a fairly soft metal. α-Fe can be subjected to pressures up to ca. 15 GPa before transforming into a high-pressure form termed ε-Fe discussed below. Magnetically, α-iron is paramagnetic at high temperatures. However, below its C… The iron-carbon phase diagram is widely used to understand the different phases of steel and cast iron. Both steel and cast iron are a mix of iron and carbon. Also, both alloys contain a small amount of trace elements. The graph is quite complex but since we are limiting our exploration to Fe3C, we will only be … See more Phase diagrams are graphical representations of the phases present in an alloy at different conditions of temperature, … See more
