Use the Fe-C phаse diаgrаm belоw tо answer the fоllowing questions. A Fe-C alloy with a very high amount of carbon (3.5% or higher) is called “pig iron”. At a temperature of 600 °C and 4.3% carbon: a. Which phase(s) is/are present? b. What is the composition of each phase? c. What is the phase fraction of each phase at this temperature and composition? Pig iron is very brittle and not very useful. To convert it into more useful (lower carbon) forms, a process called decarburization takes place where air is passed over the pig iron. This process causes the carbon in the pig iron to react with oxygen to form carbon dioxide, and reducing the overall carbon content. d. If the carbon content is reduced through this process from 4.3% to 3.0%, how does the carbon content (composition) change for each of the phases at 600 °C? Note: Do not forget to take a photo of your scratch papers and send it to the email address given in the Instructions within 30 minutes after you submit your exam to be able to receive credit.
