Critical angle technique for measuring index of refraction of metals that have an index less than unity in extreme ultraviolet
Platinum and palladium distribution in iron meteorites and ordinary chondrite metal phase spectrographically determined
Metal boot splices hard sheathed instrumentation cables used with high temperature strain gages and thermocouples. Silver brazing the conductors together, hermetically seals the splice. This boot is a highly reliable sealed splice which is equally effective at cryogenic temperatures, high temperatures, nuclear environments, and combinations of the above.
Fabrication processes for producing refractory metal alloy wire
Physical and mechanical properties of rhenium, technetium, hafnium, noble metals, and related alloys reviewed in terms of availability and costs
Adhesive properties of metal, glass, ceramic, polymer, and mineral combinations in ultrahigh vacuum
Compatibility of refractory metals with liquid Hg, Cs, K, Na and Li, noting resistance to corrosion
Metal-nonmetal transition in n- and p-type Si from high magnetic field galvanometric measurements, noting abnormally large magnetoresistance accompanied by Hall coefficient increase
Etchant containing chloroplatinous or chloroplatinic acid greatly reduces contact resistance between metallic surfaces. Etching results in a monolayer plating of platinum on the wafer surface, preventing oxide growth.
Refractory metal alloys metallurgy and technology - Conference, Washington, D.C., April 1968
Weldability and thermal stability of refractory metal alloys
Effect of oxygen contamination on weldability of refractory metal alloys
Long-time temperature stability of refractory metal alloys and weldability determinations
Production of small diameter refractory metal alloy wires for superalloy reinforcement
Strength of metals and alloys - Conference, Pacific Grove, California, August-September 1970
Apollo 12 lunar soil particles observation for reduced metal meteoritic inclusions, suggesting shock impact effects during meteoritic bombardment of moon
A description is given of the design and fabrication of candidate flame-resistant woven and knitted fabrics, tapes, webbings, and cords as replacements for those items used in the Apollo spacecraft which were previously made of nylon and polyester. Structures made from Chromel R metal fibers (74% Ni, 20% Cr, 2-1/2% Fe, 2-1/2% Al, 1/2% Si, 1/2% Mo), Beta glass fibers and high-temperature organic fibers such as PBI (polybenzimidazole) were developed and evaluated. The feasibility of improving the performance of selected fabrics by using CNR (carboxy nitroso rubber) or other nonflammable coatings were also investigated.
A glass suitable for glass-to-metal seals that has a resistance to attack by moisture and a high coefficient of linear thermal expansion is introduced. Linear expansion covers the range from 12 to 14 x 10 to the minus 6 C between room temperature and 500 C. The glass is essentially composed of, by molar percent, about 9% of K2O, about 10% of Na2O, about 70% of SiO2, about 6% Al2O3, and about 5% of MgO.
