Properties of High-Temperature Ceramics and Cermets: Elasticity and Density at Room Temperature

Description: From Introduction: "The present paper contains detailed descriptions of the methods used in calculating both the elastic constants and the statistical parameters. These detailed descriptions have been included for two reasons: (1) To leave no doubt as to the exact procedure, and (2) to act as a guide to other workers who might wish to make similar determinations."

Table of wavenumbers: Volume 1, 2000 A to 7000 A

Description: From Extension of Tables: "Because of its range and size, this table of wavenumbers is in two volumes, Volume I presenting wavenumbers for all wavelengths between 2000 and 7000 A, and Volume II giving wave-numbers for all wavelengths from 7000 A to 10000000 A=1 mm. In some cases Volume I may suffice for ionic spectra, and in others Volume II may be adequate for molecular spectra, but in general both volumes will needed to cover the entire range of spectral wavelengths measured in standard air."

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 desi… more

Temperature-Induced Stresses in Solids of Elementary Shape

Description: Report discussing how solids subjected to non-uniform temperature change develop internal stresses determined by, (1) the temperature distribution within the solid, and (2) certain physical constants of the material. For two varieties of heating, the equations determining stress have been put in convenient form for practical use, and tables of certain temperature functions show how to determine stresses in a slab, in a cylinder, or in a sphere subjected to either of two modes of heating. The te… more

Vibration-Rotation Structure in Absorption Bands for the Calibration of Spectrometers From 2 to 16 Microns

Description: Reports discussing bands of common gases that have been tabulated and remeasured wherever necessary from 2 to 16 microns to obtain an accuracy of about 0.03 cm-1 throughout the region and to provide good calibrating points at frequent intervals. Some 600 rotation-vibration lines are illustrated in 20 spectrograms and wavenumbers are listed in companion tables with considerable intercomparison with worthy data obtained in other laboratories. The absorption bands were remeasured or calibrated by … more
