2. a). Draw the microstructure of the PbSn alloy obtained by cooling through the eutectic point. What are the phases and structures presenting in this eutectic structure? Label them. b). Draw the microstructure of the hypoeutectoid and hypereutectoid steel cooled below the eutectoid temperature. What are the phases and structures? Label them. c). Using the phase diagrams presented in the lecture notes and textbook, give examples of eutectic and eutectoid reactions. Describe the composition, temperature, and phase change
