A common automotive grade ductile iron casting targets the carbon equivalency to 4.54. If the desired carbon content is 3.55 to 3.70% carbon, what is the range of silicon required to produce this type of ductile iron? How much of this alloy is eutectic?
Cast iron just like steel has wide applications. It is an alloy with carbon content in excess of about 2%C (usually between 2.5 and 4.3%C) and Si content in excess of 0.5%. The microstructure of cast iron after solidification influences the final properties of the casting From the iron carbon phase diagram above answer the following questions: a) Calculate the volume fraction of ledeburite (eutectic component) present in the alloy containing 3%C after solidification under: i) equilibrium conditions ii) fully...

Use the iron-carbon phase diagram below to answer the following questions. For phase mass fractions and composition, it is expected that you will use a straight-edge and ruler (or electronic equivalent). Note that there is a similar diagram in Chapter 10 of the Callister text if you would like to use it for reference. For the solid phase names, please use the Greek letter notation (alpha, gamma, delta, etc.) or the corresponding English nomenclature (ferrite, austenite, etc.) At what temperature does pure iron...
create a project that you would like to lead as the case for this course. You must create a project plan that lasts at least 3 months and involves a project team of at least 6 members. The project may occur in a for-profit or non-profit organization, including a church or school. The project will be comprised of several components, using Gray & Larson as a guide
