14-Year 113Cd

Description: The half lives of Cd/sup 113m/ and Cd/sup 115m/ have been redetermined to be 14 sintering time 2 years and 44.2 sintering time 0.5 days, respectively. The ratio of Cd/sup 113m/Cd/sup 115m/ yields from thermal-neutron fission of U/sup 235/ is 0.27 sintering time 0.03, and the ratio of (n, ) formation cross sections is 0.31 sintering time 0.03. Combination of these ratios with literature values for the Cd/sup 115m/ fission yield and (n, ) formation cross section gives (1.9 sintering time 0.2) x 1… more

Absorption of Organic Acids on Thoria

Description: The adsorption of acetic and oleic acids on the surface of thoria was studied by means of infrared spectroscopy. An infrared analysis of the adsorbates before and after adsorption using differential double bean methods indicated that the adsorption of organic acids on thoria surfaces occurs by an esterification reaction between the organic acid and the hydroxylated thoria surface. Ammonia vapor will not adsorb on thoria, indicated the basic character of the hydroxylated surface.

Aging of Al-Li Alloys - Part I

Description: Technical report outlining experiments on aluminum-lithium alloys. From Abstract: "Aluminum-lithium alloys are subject to precipitation from solid solution, and may be age hardened by the same techniques used for more common aluminum alloys. Spherical particles of precipitate were observed with the electron microscope in 1.5% and 2.8% Al-Li alloys after aging for times comparable to those required to produce maximum hardness. Rod-shaped particles that were oriented parallel to either the (110) … more

Air Diffusion in the Air Operating Water Flask. Section I. Test Results DL-S-205 (T-641110)

Description: The purpose of the test was to determine the effect of continuous air pressurization of the Valve Operating System water flask on the the oxygen concentration of the water in the flask. Oxygen concentration in the Valve Operating System water flask increased during the testing period of seventeen days. It cannot be determined from the data obtained if equilibrium oxygen concentration was reached. The distribution of oxygen in the flask at the end of 17 days varied from approximately 12 ppm in t… more

An Analysis of Several of the Variables Encountered in Low Cycle Fatigue

Description: Upon analyzing some data by the author and two other investigators on 2024-T4 aluminum alloy, it is shown that the phenomena of low cycle fatigue in the extremely low cycle range is more complicated than assumed to date. The interrelationship of the mean, alternating, maximum and minimum strains is developed. The log E - log N curve is examined and the effect of the mean strain on the low cycle fatigue life is presented.

An approach to the study of solid state bonding

Description: This report constitutes a review of theory, experimental approach, and means of evaluation involved in the program "An Approach to the Study of Solid State Bonding." Inasmuch as the experimental activity ceased prior to the end of the contract period, adequate data are not available with which to illuminate the area of investigation; therefore, this report should not be considered as a report of a completed project.

The Armour Dust Fueled Reactor (ADFR). Final Report Covering the Period February 21, 1958 to February 21, 1959

Description: Dust circulation studies were conducted in a 2-in.diam. glass tubing loop, 5 x 5 ft, at gas velocities of 100 and 150 fps. Most of the studies were done with Al/sub 2/O/sub 3/ in air, but some were done with U0/sub 2/2 in N/sub 2/ . Two-group criticality calculations for a graphite-reflected and moderated U/ sup 235/ burner gave approximate values of core size and fuel concentration. Investigation of axial variations in fuel density indicate that the axial neutron flux and power distributions d… more

Behavior of Bond Under Dynamic Loading

Description: The objectives of this research program are to determine bond strength under dynamic loading, to compare bond strengths under static and dynamic loading, and to test the adequacy of ACI Building Code bond requirements for structural elements subjected to blast loads. The tests have shown that local static bond strengths may be as high as 0.75 fc and that under dynamic loading this strength increases to fc. For all practical lengths of embedment of bars, steel failure is to be expected both unde… more
