Effect of machining damage on tensile properties of beryllium

Description: It is well established that damage introduced at the surface of beryllium during machining operations can lower its mechanical properties. Tensile tests were conducted to illustrate this on beryllium presently being used for parts in the W79 program and similar to the new powder-processed beryllium specified for production (tentative specification MEL 76-001319). The objective of this study is to quantitatively illuminate the importance of controlling machining damage in this particular grade o… more

Cryoforming evaluation using gold-5% copper

Description: This report deals with gold-5 percent copper, which exhibited serious instability even in its higher strength states. The uniaxial specimens in this investigation make such instabilities appear even worse. The major effect of higher strain rates and lower forming temperatures was to extend the homogeneous deformation range, which generally allowed higher attainable strengths. Biaxial testing could suppress the low-strength instabilities but probably not the higher-strength instabilities. Howeve… more

Assessment of methods for analyzing gaseous mixtures of hydrogen isotopes and helium

Description: Mass spectrographic methods have served well in the past to analyze gaseous mixtures of the hydrogen isotopes. Alternate methods of analyses are reviewed which offer wider ranges and variety of isotopic determinations. This report describes possible improvements of the mass spectrographic determinations, gas chromatography, anti-Stokes Raman spectroscopy, microwave-induced optical emission spectroscopy, and methods of measuring tritium using radiation detection devices. Precision, accuracy, lim… more

Silicon materials task of the low cost solar array project (Part 2). First Quarterly report, 1 October 1975--31 December 1975. Research report 76-9C4-SIMAT-R1

Description: The objective of this program, Part 2 of the Silicon Materials Task, is to develop and define purity requirements for solar cell grade (SG) silicon material by evaluating the effects of specific impurities and impurity levels on the performance of silicon solar cells. The basic approach of the program is to establish, as unambiguously as possible, what concentrations of the impurities commonly found in silicon starting material (metallurgical grade silicon) can be tolerated in silicon crystals … more

Equation of state of water

Description: An equation of state of water is constructed in the density range between 2 g/m/sup 3/ and 4 x 10/sup 2/ Mg/m/sup 3/ and in the temperature range between 0.025 eV (room temperature) and 25 keV by combining several theoretical codes and experimental data. The liquid-vapor phase change, ionization process, and chemical equilibrium among dissociation products of water are all considered. Theoretical results and experimental data are compared and several interesting aspects of the thermodynamics of… more

Investigation of fracture in pressurized gas metal arc welded beryllium

Description: Premature failures during proof testing of pressurized-gas-metal-arc (PGMA) welded beryllium assemblies were investigated. The failures were almost entirely within the beryllium (a forming grade, similar to HP-10 or S-240), close to and parallel to the weld interface. The aluminum-silicon weld filler metal deposit was not centered in the weld groove in the failed assemblies, and failure occurred on the side of the weld opposite the bias in the weld deposit. Tensile tests of welded samples demon… more

Freeze block testing of buried waste lines

Description: An investigation was conducted to demonstrate application of freeze blocking in waste transfer lines such that a hydrostatic pressure test can be applied. A shop test was conducted on a 20-foot length, 3-inch schedule 40, carbon steel pipe using a coolant of dry ice and Freon. The positive results from these tests prompted a similar employment of the freeze block method in hydrostatic pressure testing the feed inlet leading to 241-S-101 Waste Tank. This pipeline is a 3-inch schedule 10, stainle… more

Reclaiming process for scrap deuterated polyethylene (CD/sub 2/)

Description: A laboratory version of a process to clean contaminated deuterated polyethylene (CD/sub 2/) was modified slightly and scaled up to produce 2 lb of clean, reusable CD/sub 2/ polymer. A complete cycle of the process is: (1) Melt the CD/sub 2/ polymer at 30 vol percent in xylene at 105 to 110/sup 0/C. (2) Pressure filter the hot solution at 103 to 138 kPa (15 to 20 psi). (3) Cool the solution to precipitate the polymer and separate it from the liquor. (4) Vacuum dry the precipitate at about 266 Pa… more
