I purchased this book for a course in materials science. The course was structured as an independent study. I was responsible for studying the materials and I would take quizzes through e-mail. This book was my primary source of instruction for the course. Where the book could not support me in the quizzes, it was necessary to seek information elsewhere. My judgement of this book, therefore, is based on its thoroughness, mathematical rigorousness and its ability to explain concepts. Most of the topics covered in the course were well presented by the book. In particular, chapter 3, on the Structure of Crystalline Solids, was very well done. In general the writing style is good. The use of many figures and diagrams enhanced the explanations of physical phenomenon. I highly recommend it for an intuitive viewpoint into material science. Where the book falls down is in the realm of calculation. There are too few formula given. Where they are given, there are too few examples on their use. Chapter 6 on the Mechanical Properties of Metals, and chapter 9 on Phase Diagrams, are sections that failed in this regard. However, the books lack of over-reliance on formula and mathematics is a great enhancement for those just beginning an exploration of the science or a career in engineering. Too many numbers on a page would be a discouragement to those wishing to enjoy the material. Therefore, I would recommend this book as a sophomore level introduction to Material Science, for which, in fact, it has been written.
