1. Briefly cite the differences between recovery and recrystallization processes. 2. Briefly explain why small-angle grain boundaries are not as effective in interfering with the slip process as arc high-angle grain boundaries. 3. Briefly explain why HCP metals arc typically more brittle than FCC and BCC metals. 4. Describe in your own words the three strengthening mechanisms discussed in this chapter (i.e., grain size reduction, solid-solution strengthening, and strain hardening). Be sure to explain how dislocations are involved in each of the strengthening techniques.
