Constitufion of Binary Alloys

Maz H a n s a , Managing Direotor, MetThis reviewer has only one point to offer which it is believed would have contributed a great deal t o the usefulness of the work. As it stands. the volume is simply a well-organized collection and summary af literature. Thus, as an example in the chapter on radium, a "calculated" heat of reaction of radium with water is given a8 90 kcal/g atom; yet the standard A H " for Rat+(aq), a much mare fundamental quantity, is omitted. A deposition potential for radium is given a8 -1.718 v (calomel) (which must surely correspond to oxide and/or hydroxide formation) although the st,andard reduction potential of -2.92 v is not listed. No mention is made of the atomic weights of mdium (and the other elements) derived from nuclear decay data, although such Sources almost always lead to a more accuratte value. An estimated ionic C I ~ E talradius for Rat+ is given as 2.45A in the same sentence with an experimentally determined one of 1.52 A from RaF2 with no comment as to the validity of either. One would have hoped that a more scholarly and selective appraisal of the literature could have been made by a. man so obviously a leading contributor to the field.

Seldom does one find as complete a reference u-ork as this in a ~inglcvolume. The data are recent (some 1957 items are included), inclusive (1286 systems are covered), and conveniently presented (the 684 phase diagrams are in atomic per cent rather than weight per cent). Crystallographic data likewise are provided with a completeness that includes lattice spacings of intermediate phases. The reader is impressed by the vast amount of informstion which must have been critically evaluated in the preparation of this work. The following is typical: "According to thermal, microscopic and electrical investigations and roentgenographic measurements. . . ." Obviously the specialist will find this book indispensable. I t belongs in every academic lihrmy whieh provides complete reference enversge of chemistry and related fields. Even students in elementary physical chemistry courses should discover this compendium of information at the same time they discover the phase role.

This second volume about rheology, the science of deformation and flow, not only includes more about theoretical treatments but also dedls ~specificslly with organic glasses, raw elastomers, cellulose derivatives, fibers, snd asphalts. Also there is a chapter dealing with the earth's interior whieh, interestingly enough, followa the general principles "derived from the study of less 'immohile' objects." I n Chapter 111, T. Rhee and H. Eyring present their relaxation theory of transport phenomena with much evidence to show its general applicability. The theory encompasses more than any other and is a partial answer to the cry raiaed in Volume 1for a generalized theory of flow and deformstion. There are two chapters on experimental techniques-me on fluids that overemphssizos the utility of the concentric cylinders method for obtaining viscosities and one about measurements on viscoelastio bodies. The chapters in the second volume appear to be more uniform in style and outline than those in Volume 1 (see THIS JOURNAL, 34, A284 (1957)). There are even fewer obvious errors, although the (Continued on page A110)
