[Short Reviews]

Abstract

THE popularity of this book is explained by the way in which the authors have succeeded in combining clarity with brevity. The treatment of fundamentals is, however, a little superficial in some respects. In the new chapter on plastic deformation, for example, no hint is given that metallic crystals are anything but perfect in structure, and one would prefer to see the early chapters, on the equilibrium diagram, extended at the expense of the final chapter on laboratory methods. The list of alloys given in the appendix might be replaced with advantage by a select bibliography. Printing, illustrations and binding are excellent.
