A slowly cooled steel shows an equilibrium microstructure continuing 50% pearlite and 50% ferrite at room temperature.
a) Using the reverse lever rule, estimate the carbon concentration in this alloy
b) Describe the microstructure that would be obtained (at equilibrium) if this metal is heated 50 degrees above the A1 temperature? For the alloy being considered what is this temperature?
c) What microstructure would exist in this metal if it heated to 100 degrees above the A3 temperature and held at for some time to reach thermal equilibrium? For the alloy being considered what is this temperature?
