Preface
Science-led or Design-led? Two approaches to materials teaching
The traditional approach to materials teaching starts with fundamentals: the electron, the atom, atomic bonding, and packing, crystallography, and crystal defects. Onto this is built alloy theory, the kinetics of phase transformations and the development of the microstructure on scales made visible by electron and optical microscopes. This sets the stage for the understanding and control of properties at the millimetre or centimetre scale at which they are usually measured. This science-led approach is grounded in a deep physical understanding of the origins of material properties but gives less emphasis to the behavior of structures and components in service, or methods for material selection and design (the schematic below, reading from left to right).
Science-led and Design-led approaches to materials teaching, and the length scales involved.
The alternative approach is design-led (the schematic, reading from right to left). The starting point comprises the requirements that materials must meet if they are to perform well in a given design. To match material to design requires a perspective on the range of properties they offer, how these properties combine to limit performance, the influences of manufacturing processes on properties, and the environmental impact over the product life-cycleall coupled to the need to access data and expertise to evaluate them. Once the importance of each property is established, there is a clear platform and motivation from which to drill down, so to speak, to examine the science that lies beneath itvaluable because an understanding of the fundamentals itself informs material choice, processing, and usage.
Each approach has its place. The best choice depends on the nature of the course and the aspirations of the student. If the intent is to educate future scientific researchers, the first is the logical way to go. If it is any branch of engineering, design, or applied industrial research, the second makes better sense. This book follows the second, design-led, approach, while providing a balanced treatment of the fundamentals.
What is different about this book?
There are many books about the science of engineering materials; many more about design. What is different about this one?
First, its design-led approach , specifically developed to guide material selection and understanding for a wide spectrum of engineering courses. The approach is systematic, leading from design requirements to a prescription for optimized material choice, illustrated by numerous case studies. Practice in the approach is provided by worked Examples in the text and Exercises at the end of each Chapter.
