### Project Contract For Kim Ballentine

This is an outline for my example of Fe-Fe3C phase diagram:

The Fe-Fe3C Phase Diagram Fig 1. Fe-Fe3C Phase Diagram. Materials Science and Metallurgy, Herman W. Pollack, Prentice Hall, 1988, which will be given to the Sci-Viz group to scan by Tue Apr 16.

First, I will make a paragraph about the allotropic changes such as ferrite, austenite, cementite, pearlite (proeutectoid and hypoeutectoid), and I will talk briefly about ledeburite and graphite in cast iron. I will also talk about the eutectoid reaction.

The second section will be on calculating phases at the eutectoid composition line. I will also calculate the amount (number of grams) of carbide that form per number of grams of steel. I will calculate the amount of pearlite given a composition and a temperature. I will also ask what temperature will be required if a given steel must be heated into the austenite range. The format of the problem will be like one would see in a test: Given a phase diagram, calculate..., and give parts A-D to answer.

After I give solutions to all parts of the problem, I will have a link to the applications of steel.

Then I will have a link to my extra-credit part of the class project, the T-T-T diagram.

At the bottom of the page with the Fe-Fe3C phase diagram, I will put "Created by Kim Ballentine" with a link to my home page.

Here is an outline for my example using the Fe-Fe3C T-T-T diagram:

The Fe-Fe3C T-T-T Diagram Fig 2. Fe-Fe3C T-T-T Diagram. Physical Metallurgy Principles, Reed & Hill, PWS Publishing Co., 1994, which will be given to the Sci-Viz group to scan by Tue Apr 16.

First I will talk about the time-temperature paths, 1 through 4, and I will give another figure representing these paths: Fig 3. Fe-Fe3C Time-Temperature Paths. Same reference as Figure 2.

I will ask several questions about the T-T-T diagram in the same format as the phase diagram example. I will ask the room-temperature structure, and ask to calculate the time needed for the transformations. I will ask to calculate the amount of each phase found at certain temperatures.

The next section will give solutions to all the questions I ask.

I will have another link to the applications of steel. I will have a link back to the Fe-Fe3C phase diagram, and once again, I will put my name at the bottom of the page with a link to my home page.
