Effect of Rivet Holes on the Ultimate Strength Developed by 24S-T and Alclad 75S-T Sheet in Incomplete Diagonal Tension

Description: Strength tests were made of a number of 24S-T and Alclad 75S-T aluminum-alloy shear webs to determine the effect of rivet or bolt holes on the shear strength. Data were obtained for webs which approached a condition of pure shear stress as well as for webs with well-developed diagonal tension. The rivet factor, (pitch minus diameter) divided by pitch, was varied from approximately 0.81 to 0.62. These tests indicated that the shear stresses on the gross section were nearly constant for all values of the rivet factor investigated if the other properties of the web were not changed.

Dynamic Determination of the Compressibility of Metals

Description: Abstract: "Equation of State data for duralumin in the pressure range from 0.1 to 0.3 megabar have been determined dynamically by measuring shock and free surface velocity electrically in a place of 24 ST duralumin which has been stressed by a high explosive donation. The theory is presented which allows comparison with data obtained by other experimenters, requiring the relationship between pressure and compression either at constant entropy or constant temperature. The empirical form chosen for the equation of state p = αμ + βμ-2 expresses the pressure as a quadratic function of the compression. Experimental techniques are described in detail. Five points are given for equation of state of duralumin in the pressure range from approximately 0.15 megabar to 0.33 megabars. Some data are also presented for cadmium and steel."

Metal Complexes of 2,3-Quinoxalinedithiol

Description: A series of new planar complexes with the dianion of 2,3-quinoxalinedithiol ligand has been prepared. The complexes have been characterized from the study of their analyses, magnetic moment, conductance, polarograms, electron spin resonance spectra, and electronic spectra, and compared with the available data on the corresponding maleonitriledithiolene and toluene-3,4-dithiolene complexes.

Standard Operating Procedure for Rolling 2.75% Enriched Metal at Simonds Saw and Steel Company. Production Order No. 296. (Section

Description: Results indicate the following: buttons of zirconium di-boride, tantalum carbide, and titanium carbide cannot be obtained by electron beam melting; small ingots or buttons of boron can be obtained by electron beam melting, but the boron is still very brittle; and the chromium content of beryllium is reduced by electron beam melting.

Description: In a continuation of the Hanford-Battelle cooperative program, the combined use of the vibrational-compaction and gas-pressure-bonding processes for fabricating UO/sub 2/ fuel elements was studied. Particuliar emphasis was placed on the use of agglomerated micronized UO/sub 2/ to overcome nonuniformities in the vibrationally compacted pressurebonded fuels. Inconel-X-clad fuel rods were gas-pressure bonded at 2100 deg F for 3 hr at 10,000 psi to evaluate the use of micronized UO/sub 2/ agglomerated by cold high-energy-rate forming methods. Fuel densities from 88 to 93% of theoretical were attained. A limited parallel study was also conducted a evaluate hydrostatic pressing as a method of agglomerating micronized UO/sub 2/. Tap density increased from 20 to 25% for the as-received micronized oxide to 41% for the hydrostatically agglomerated plus 200-mesh powder. Studies of the effects of prior cold work and gaspressure bonding on the mechanical and physical properties of types 304L and 347 stainless steel were conducted. Prior cold work in the range of 35 to 50% gave a pressurebonded structure having a fine grain size. (auth)

Analytical Methods for Certain Metals Including Cerium, Thorium, Molybdenum, Tungsten, Radium, Uranium, Vanadium, Titanium and Zirconium

Description: From Introduction: "This chapter indicates the methods of determining several of the alloy metals when occurring together in the same sample. Most materials seldom contain more than two or three of these elements, but considerable time may be saved if determinations can be combined. Details of the analyses and separations are not given here, as they have been covered more fully in other chapters. Whenever possible, reference is made to the particular chapter. Only sufficient directions have been given to outline the method of procedure, actual conditions for the separations being presented on other pages."

Study of the Micro-Nonuniformity of the Plastic Deformation of Steel

Description: The plastic flow during deformation of real polycrystalline metals has specific characteristics which distinguish the plastic deformation of metals from the deformation of ordinary isotropic bodies. One of these characteristics is the marked micro-nonuniformity of the plastic deformation of metals. P.O. Pashkov demonstrated the presence of a considerable micro-nonuniformity of the plastic deformation of coarse-grained steel wit medium or low carbon content. Analogous results in the case of tension of coarse-grained aluminum were obtained by W. Boas, who paid particular attention to the role of the grain boundaries in plastic flow. The nonuniformit of the plastic deformation in microvolumes was also recorded by T.N. Gudkova and others, on the alloy KhN80T. N.F. Lashko pointed out the nonuniformity of the plastic deformation for a series of pure polycrystalline metals and one-phase alloys. In his later reports, P.O. Pashkov arrives at he conclusion that the nonuniformity of the distribution of the deformation along the individual grains has a significant effect on the strength and plastic characteristics of polycrystalline metals in the process of plastic flow. However, until now there has not existed any systematic investigation of the general rules of the microscopic nonuniformit of plastic deformation even though the real polycrystalline metals are extremely simple with regard to structure. In the present report, an attempt is made to study the micrononuniformity of the flow of polycrystalline metals by the method of statistical analysis of the variation of the frequency diagrams of the nonuniformity of the grains in the process of plastic deformation.

The Further Development of Heat-Resistant Materials for Aircraft Engines

Description: The present report deals with the problems involved in the greater utilization and development of aircraft engine materials, and specifically; piston materials, cylinder heads, exhaust valves, and exhaust gas turbine blading. The blades of the exhaust gas turbine are likely to be the highest stressed components of modern power plants from a thermal-mechanical and chemical standpoint, even though the requirements on exhaust valves of engines with gasoline injection are in general no less stringent. For the fire plate in Diesel engines the specifications for mechanical strength and design are not so stringent, and the question of heat resistance, which under these circumstances is easier obtainable, predominates.

Micromechanical Study of Metals

Description: The Institut Scientifique Experimental des Transports at Moscow established toward the end of 1925 had since its inception included in its program the study of the mechanism of plastic deformation and the problems associated with it with reference to the materials of the means of transport. Before the program thus determined upon could be carried out, it was necessary to adopt a method of research, or, more exactly, a system of such methods. Because of the modest equipment of the laboratory of the recently established institute, the choice of any particular method was determined not only by the advantages it offered but also by the resources available. As a result of a series of studies and investigations, a method was determined upon which in this paper will be denoted as the micromechanical method. The underlying basis of this method is already known. As will be seen from the description that follows, the micromechanical method is merely a combination of the micrographic study of plastic deformations with mechanical tests on small specimens. It is a well-known fact that a number of investigators have largely employed and still are employing these two procedures and have thereby obtained good results. The authors of the present paper have found it useful to combine the two methods, by making the two studies simultaneously on the sane specimen.

Description: The crystal structures of alloys 61, X-40,X-50, 422-19, 6059, and Vitallium, derived from x-ray diffraction, are discussed. The alloys have been, or are being considered for use in gas turbine applications. The predominant phase was a solid solution of the face centered cubic type of the principal constituent elements.The lattice parameters were found to be between 3.5525 and 3.5662.
