Band structure of noble metal alloys: Optical absorption in α-brasses at 4.2°K
M. A. Biondi, J. A. Rayne
Calorimetric optical absorption measurements at 4.2°K have been made on a representative series of α brasses over the wavelength range 0.23 to 4.0 microns using electropolished bulk specimens. Changes in the absorption spectrum below 6000 A are interpreted in the …

The Melting Point-Composition Diagram of the Zirconium-Oxygen System
Daniel Cubicciotti
The solidus curve of the zirconium-zirconium dioxide system has been investigated by observing the melting points of wires of the oxidized metal. The results show that near the melting points oxygen dissolves to the extent of 55 atom per cent. …

Solar reflectance integrating sphere
R. V. Dunkle, D. K. Edwards, J. T. Gier, J. T. Bevans
An inexpensive integrating sphere for the direct determination of the reflectance of materials irradiated by solar energy transmitted through the atmosphere of the earth is described. Reflectance and transmittance measurements of various metals, cloths, and filters are reported and are …

Thermal and electrical conductivities and spectral and total emissivities of nickel at high temperatures
S. C. Jain, T. C. Goel, I. Chandra
The method of Jain and Krishnan for measuring the thermal conductivity and other physical properties of metals at high temperatures is improved and values of these properties measured by the improved technique are reported in the temperature range 1150° to …

The emissivity of transition metals in the infrared
R. A. Seban
Absorptivities of iron, nickel, and- platinum are presented for room temperature and emissivities for temperatures of the order of 2000 deg R for wavelengths from 1 to 15 microns. These are compared to the predictions made from Roberts’ theory for …
