Tables of Einstein Functions: Vibrational Contributions to the Thermodynamic Functions

Description: From Introduction: "The recent acceptance by physicists and chemists of new values for the fundamental constants and the continued demand for expanded and convenient tables prompted the recomputation and preparation of this volume. The authors have tried to incorporate this work a number of the more desirable features of the above-cited works, particularly with respect to their use in calculations involving: Thermodynamic properties of gases; specific heats, electrical and thermal conductivity of solids; and molecular structure and spectroscopy of diatomic and polyatomic molecules. It is the hope of the authors that formal character of this publication will insure a more adequate notice and dissemination than was accorded the earlier works, thereaby reducing the probability of still further duplication of effort."

Low Temperature Mechanical Properties Of Copper and Selected Copper Alloys: A Compilation From the Literature

Description: From Abstract: "In the past 60 years considerable data have been accumulated concerning the mechanical properties of copper and its alloys.It was felt that there was great need to adequately document these results in one publication. Therefore a unique type of compilation is presented. The compilation is divided into four parts. The first section is intended for quick reference use for those who are interested in average values. The second section includes data from most of the investigators who have published results on the mechanical properties of copper and its alloys. The third section is composed of tables classifying the investigations which were not in section two. The fourth section section lists, in alphabetical order, all references used."

Mechanical Properties of Structural Materials at Low Temperatures: A Compilation From the Literature

Description: From Introduction: "The data are presented with the idea that an engineer who is making initial calculations on equipment for operation at cryogenic temperatures is more interested in obtaining quickly a definite figure that he in evaluating the experimental data given in several detailed reports on the same material. The graphs and tables presented here, consequently, represent an attempt by the authors to perform evaluation of data which have appeared in the literature and to present the design engineer with the result."
