Description of  The Equations of Materials

This primer describes important equations of materials and the scientists who derived them. It provides an excellent introduction to the subject by making the material accessible and enjoyable. The book is dedicated to a number of propositions: 1. The most important equations are often simple and easily explained 2. The most important equations are often experimental, confirmed time and again 3. The most important equations have been derived by remarkable scientists who lived interesting lives. Each chapter covers a single equation and materials subject, and is structured in three sections: first, a description of the equation itself second, a short biography of the scientist after whom it is named and third, a discussion of some of the ramifications and applications of the equation. The biographical sections intertwine the personal and professional life of the scientist with contemporary political and scientific developments. Topics included are: Bravais lattices and crystals Bragg's law and diffraction the Gibbs phase rule and phases Boltzmann's equation and thermodynamics the Arrhenius equation and reactions the Gibbs-Thomson equation and surfaces Fick's laws and diffusion the Scheil equation and solidification the Avrami equation and phase transformations Hooke's law and elasticity the Burgers vector and plasticity Griffith's equation and fracture and the Fermi level and electrical properties. The book is written for students interested in the manufacture, structure, properties and engineering application of materials such as metals, polymers, ceramics, semiconductors and composites. It requires only a working knowledge of school maths, mainly algebra and simple calculus.
