This is a really good text for the introduction to undegraduates of the scientific principles which underpin physical metallurgy, from thermodynamics to kinetics. Rather than simply starting with phase diagrams, and using them to desribe the progress of metallurgical changes which occur, for example, in alloy solidification or heat treatment, the authors set out to explain the fundamental analytical steps which lead to these phase diagrams. This gives students a deeper understanding of phase change. The development of the theory is rapid, with the first chapter taking us from introductory thermodynamics to ternary phase diagrams. The thermodynamics is not introduced quite from scratch, however, and students will need to have some prior knowledge of the subject, perhaps through a rudimentary engineering thermodynamics course. Diffusion, kinetics and solidification are well covered in the book. Each chapter has a list of references for those who would like to study the topics covered in more depth. Useful exercises (and even more useful - solutions!) are given at the end of each chapter. The book is very readable. It may also prove useful as background reading or revision material for postgraduate students and other researchers in metallurgy.
