Unformatted text preview: l): After cooling slowly to room temperature from 1000 oC, an Fe ­1.0 wt% C alloy has the microstructure described by the image given at the right. The light contrast corresponds to cementite, and the dark contrast corresponds to ferrite. The Fe ­Fe3C phase diagram is given on the following page. A. Draw a well ­labeled plot of carbon concentration as a function of position along the line a ­b in the inset. B. Determine the weight fraction of ferrite and the weight fraction of cementite in this sample. Assume that the maximum solid solubility of C in ferrite is 0.02 wt%. C. Draw a well ­labeled plot...
