• Slide 1: Title: The Iron–Carbon
System
• Steels and cast irons are
essentially iron–carbon alloys,
making the iron–carbon
system possibly the most
important binary alloy system
• This system can be divided into
two parts: an iron-rich portion
and the other for compositions
between 6.70 and 100 wt% C
• All steels and cast irons have
carbon contents less than 6.70
wt% C
• The iron–carbon system's
phase diagram is discussed in
this section

, • Title: The Fe–Fe3C Phase Diagram
• A portion of the iron–carbon phase
diagram is presented in Figure 9.24
• Pure iron experiences two changes in
crystal structure before it melts upon
heating
• The stable form at room temperature
is ferrite or α-iron, which has a BCC
crystal structure
• Ferrite undergoes a polymorphic
transformation to FCC austenite or γ-
iron at 912°C (1674°F)
