CHAPTER 9 1. Ferrite is the name of the structure of a solid solution of steel at 1200 F that contains a very small percentage of carbon (perhaps 0.02% ).Assume that this steel has not been previously heat treated. 2. Cementite is the name of the structure of iron at room temperature that contains 6.67% carbon. Assume that this metal has never heat treated. 3. Pearlite is the name of the structure of a solid solution of steel at room temperature that contains 0.8% carbon. Assume that this steel has never heat treated. 4. The carbon in a sample of pure pearlite approximately is 0.8%. 5. Austenite is the structural form of steel that occurs only at elevated temperature .It is not magnetic. 6. The structural will change back to ferrite and pearlite, when steel is slowly cooled from a high temperature to room temperature. 7. Of the following types of iron-carbon which is the hardest: austenite, cementite, ,ferrite , or martensite ? It is martensite.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
