72.8% 13 11 40 / 42 IRON-CARBON SYSTEM Assignment: Refer to the Iron-Carbon Phase Diagram. Consider alloys containing 0.5% C, 0.83% C and 1% C, which have been slowly cooled from the austenite region (say 1100°C) to room temperature. Answer the following questions. 1. Why is slow cooling preferred to rapid cooling? 2. Describe the transformations that occur in the complete but slow cooling process of these alloys. 3. Calculate the relative amounts and compositions of the phases present at room temperature 4. Draw the microstructure, which would result in each case. This Assignment is Due in One Week's Time.
