                                properties, and/or performance for at least one of these four materials, a summary
                                is provided in the form of one or more concept maps. A concept map is a diagram
                                that illustrates the relationships among concepts. We represent these relationships
                                by connecting arrows (frequently horizontal); each arrow points (left to right) from
                                one concept to another. The organization of these connections is hierarchical—that
                                is, a concept to the left of an arrow should be mastered before a concept to the right
                                can be understood. For each map, at least one of its concepts is discussed in its chap-
                                ter; other concepts may be treated in previous and/or later chapters. For example,
                                Figure 1.13 presents a portion of a concept map for the processing of steel alloys that
                                appears in Chapter 10.
