Classification of DMIC Reports and Memoranda by Major Subject by Anonim Pdf

To aid in quick identification and easy location of specific technical data and information in the various reports and memoranda which have been prepared and distributed by the Defense Metals Information Center, as well as by DMIC's forerunner, the Titanium Metallurgical Laboratory, a classification by major subject matter was prepared. The classification covers reports through DMIC Report 193 and memoranda through DMIC Memorandum 183. (Author).

Continued Observations on the Distribution of Stress in the Vicinity of a Crack in the Center of a Plate by L. R. Jackson Pdf

This memorandum supplements and augments information presented in DMIC Memorandum 178 (AD-422 463). In the present report, Neuber's stress equations are rewritten entirely in rectangular coordinates. In addition, numerical results have been extended to include the stress distribution around an indefinitely sharp crack. It is also shown that the stress function used in a British work for an indefinitely sharp crack yielded identical numerical results, even though the stress function was of a different type than that employed by Neuber. The Von Mises relation was chosen to delineate the area around a crack in which plastic flow is occurring. The numerical tables in this memorandum give values for the function of plane stress as well as one possible interpretation of plane strain. Values of the hydrostatic stress variant are also given for both plane stress and plane strain. (Author).

Summary of the Eighth Meeting of the Refractory Composites Working Group by E. S. Bartlett,H. R. Ogden Pdf

This memorandum summarizes information on refractory materials and composites as presented at the Eighth Meeting of the Refractory Composites Working Group in Fort Worth, Texas, January 14-16, 1964. This memorandum is based on 45 papers covering a wide variety of subjects ranging from basic studies on oxidation mechanisms to the development of specific pieces of hardware. The papers are reviewed and discussed briefly within the framework of the following four broad areas: materials technology, process technology, specific hardware applications, and evaluation techniques. Included in the section on materials technology are discussions dealing with bulk refractory materials and coatedmetal systems. Hot spraying, chemical vapor deposition, powder processes, joining, and extrusion are discussed in the section on process technology. The specific hardware applications cover rocket-motor components, nose caps, leading edges, hot skins, and fasteners. (Author).

Observations on Delayed Cracking in Welded Structures of Unalloyed Titanium Sheet by R. H. Ernst,D. N. Williams,H. R. Ogden Pdf

A brief study of delayed fracture in a seam-welded titanium panel is summarized in this memorandum. Examination of the fracture surface with electron microscopy showed that the material cleaved, failing in a brittle manner. Although the nature of the embrittlement was not clearly defined, titanium hydride phase was suspected as a prime contributor to failure. Even though the hydrogen content of the titanium was only 65 ppm, hydride embrittlement was thought to have occurred from precipitation of hydride platelets on crystal planes oriented normal to welding stresses. Other work, briefly discussed in the memorandum, has confirmed that hydride platelets in titanium can be oriented by stress and that tensile ductility of Zircaloy (which behaves similarly with respect to hydrogen, to titanium) depends upon hydride orientation. Stress-relief annealing of welded titanium structures is recommended wherever possible to minimize embrittlement by stress-oriented hydrides. (Author).
