SUMMARY
Eutectoid composition in an iron-carbon alloy refers to the specific ratio of carbon (0.76% by weight) that results in the formation of pearlite upon cooling from the alpha phase to room temperature. During this cooling process, the alloy undergoes a phase transformation where austenite decomposes into alternating layers of ferrite and cementite, creating a microstructure that enhances mechanical properties. The referenced diagrams and notes provide detailed insights into the phase changes and microstructural evolution of the alloy at eutectoid composition.
