Q-1. Explain how plastic deformation occurs on the atomistic scale. Include a discussion of dislocation motion.

Q-2. In general, are fcc or bcc phases more easily deformed plastically? Explain why in terms of both the number of and nature of slip planes for each crystal structure.

Q-3. What are some of the mechanisms (at least 3) by which polycrystalline materials may resist deformation?

Q-4. Why are materials generally stronger in compression than in tension?

Q-5. How can dislocations annihilate each other?

Q-6. Describe the process of work hardening based on dislocation motion.

Q-7. Explain why yield strength depends on grain or crystal size. You can include an equation, but also explain using words.
