A carbon steel contains 87.3 % of ferrite room temperature. Calculate the carbon content of the steel and choose the correct answer below.
O 2.11% C
O 1.15%C
O 5.65 % C
O 0.85 % C
These questions are based on a high carbon stell with a composition of 1.5%C and 98.5%Fe
1)Name the phases present and calculate the amounts of these phases just above the eutectoid temperature.
2)With equilibrium cooling just below the eutectoid temperature calculate the total ferrite.
Prove that more than 8% volume change took place when ferritic iron changes its structure to austenitic iron when heated above 723°C. Assume that iron atomic radius maintained.
