Peritectoid Reaction In Iron Carbon Diagram. Iron–carbon phase diagram showing the eutectoid transformation between austenite (γ) and pearlite Eutectoid When the solution above the transformation point is solid rather than liquid an analogous eutectoid transformation can occur For instance in the ironcarbon system the austenite phase can undergo a eutectoid transformation to produce ferrite and cementite.
Compulsory 2 marks will be given from this IronCarbon Diagram Theory in any exam IronCarbon Phase Diagram with Detailed Explanation If the percentage of the carbon is in the range of 0 to 211 % then it is called Steel and if the percentage of carbon is in the range of 211 to 667% then it is called Cast iron.
