1. Starting with a sample of a fine pearlitic steel, describe the most efficient way to form a coarse pearlitic steel.

2. Now, with this sample of a coarse pearlitic steel, describe the most efficient way to form a tempered martensitic steel.

3. Now with this sample of a tempered martensitic steel, describe the most efficient way to form a spheroiditic steel.

4. Now with this sample of a spheroiditic steel, describe the most efficient way to return to a fine pearlitic steel (i.e. the steel that you originally started with).

5. What additives to the steel would make it easier to form martensite?

6. In what form should these additives be in so that they are effective?

7. Which one of these steels above would you probably use to make a high quality hand tool and why?

8. Which one of the steels above would you probably use for a low strength application that required a large amount of plastic deformation of the component during manufacture?
