Metal Deformation Processing by F. W. Boulger,A. F. Gerds,R. L. Jentgen,G. E. Meyer,H. Ll. D. Pugh,Alan R. Rosenfield,D. E. Strohecker,Volker Weiss Pdf

As part of the Metalworking Processes and Equipment Program, information was collected on deformation characteristics of metals and their effect on processing operations. The report presents the information collected from technical engineering reports on Government contracts and from general engineering and metallurgical publications. The objective is to help the nonspecialist in recognizing the implications of scientific findings and in applying them in specific operations. This report contains a series of articles covering the following subjects: Ductile Fracture; Application of High Pressure to the Forming of Brittle Metals; Superplasticity; Lubrication in Metal-Deformation Processes; Swaging; Adiabatic Conditions in Deformation Processing; Residual Stresses produced by Deformation. These subjects are treated in two ways: (1) generalized discussions of common processes point out why specific variables must be modified in order to deform certain types of metals satisfactorily; and (2) data on the more difficult-to-form metals are used to illustrate the principles, limitations, and effects of the processes.

Fiber-reinforced Metal-matrix Composites by Curtis Maitland Jackson,H. J. Wagner Pdf

The introductory sections contain a brief discussion of the general methods of producing fiber-reinforced composites and of the theory of fiber-reinforcement of metals. The body of the report describes research on fiber-reinforced metal matrix composites, and is organized according to metal matrix materials. For convenience, the report is divided into two sections: Low density matrices (including aluminum, magnesium, and titanium and their alloys) and high density matrices (cobalt, copper and its alloys, iron, lead-tin alloys, nickel and nickel alloys, silver, tantalum, and tungsten).

Forming of Titanium and Titanium Alloys by D. E. Strohecker Pdf

This report represents a portion of the information contained in the March, 1967, revised edition of the 'Aircraft Designer's Handbook for Titanium and Titanium Alloys' which was prepared by the Defense Metals Information Center under the joint sponsorship of the U.S. Air Force Research and Technology Division, and the Federal Aviation Agency. The important techniques discussed include; (1) brake forming, (2) stretch forming, (3) deep drawing, (4) trapped-rubber forming, (5) tube bulging, (6) bending, (7) drop-hammer forming, (8) roll forming, (9) roll bending, (10) spinning, (11) shear forming, (12) dimpling, (13) joggling, and (14) hot sizing. Auxiliary metalworking operations, preparation for forming, blank heating methods, lubricants for forming and tooling materials are discussed. Other data available in the open literature have been summarized and referenced to present a comprehensive picture on the state of the art of these fabrication methods as related to titanium and its alloys.

Corrosion of Beryllium by Paul D. Miller,Walter K. Boyd Pdf

The report summarizes the corrosion behavior of beryllium. The effects on beryllium of the following environments are considered: moisture, salt solutions, acids, alkalis, gases, organic liquids, molten materials, and solid materials. Stress-corrosion cracking and galvanic effects are also discussed. A final section of the report reviews various types of coatings for protection of beryllium from corrosion by a variety of environments.

Powder Metallurgy of Beryllium by Stanley W. Porembka,H. D. Hanes,P. J. Gripshover Pdf

This report discusses the powder metallurgy of beryllium from the preparation of powders through the production from the powders of solid products. Various methods of powder compaction are presented including die pressing, isopressing, slip casting, vibration packing and explosive compaction. Sintering, and methods of elevated temperature consolidation, including vacuum hot pressing, hot isostatic pressing, forging, extrusion, and plasma spraying, are discussed. The final sections of the report cover properties of powder beryllium products, applications of beryllium prepared by powder metallurgy and current trends in the powder metallurgy of beryllium.

Joining of Titanium by Robert Edward Monroe,J. E. Mortland Pdf

This report supplies information on joining processes applicable to titanium and its alloys in sheet metal applications, primarily related directly to airframe construction. Although the material presented here does not cover all titanium joining processes, and omits such processes as plasma-arc, submerged-arc, electroslag, flash, and high-frequency resistance welding, the data presented cover materials up to 2-inches thick in some cases and the report should be useful to anyone seeking titanium joining information. The joining processes covered fall into five categories: welding, brazing, metallurgical bonding (diffusion and deformation bonding), adhesive bonding, and mechanical fastening. The fusion welding processes that are discussed in detail include gas tungsten arc, gas metal arc, arc spot, and electron beam. The resistance processes give extended coverage are spot, roll spot, and seam welding. (Author).
