When the relationships between the structure, properties, and processing of materials are fully understood and exploited, materials become enabling—they are transformed from stuff, the raw materials that nature gives us, to things, the products and technologies that we develop as engineers. Any technologist can find materials proper ties in a book or search databases for a material that meets design specifications, but the ability to innovate and to incorporate materials safely in a design is rooted in an understanding of how to manipulate materials properties and functionality through the control of materials structure and processing techniques. The objective of this textbook, then, is to describe the foundations and applications of materials science for college-level engineering students as predicated upon the structure-processing-properties paradigm. ties in a book or search databases for a material that meets design specifications, but the ability to innovate and to incorporate materials safely in a design is rooted in an understanding of how to manipulate materials properties and functionality through the control of materials structure and processing techniques.
