Exercises

This chapter presents photographs of microstructures similar to those discussed in the previous chapters. The photographs are meant as exercises, to be studied and interpreted by the reader. We have given only the essential information in the figure captions, and our interpretations of the structures are given at the end of the section. The subjects of the problems follow the sequence of treatment in the book. The reader may not always agree with our interpretations, but the main purpose of this chapter is to provide some examples of how information can be obtained from thin sections and which arguments can be used for their interpretation.
