Book Metal Removal by Electrochemical Methods and Its Effects on Mechanical Properties of Metals

Download or read book Metal Removal by Electrochemical Methods and Its Effects on Mechanical Properties of Metals written by John A. Gurklis and published by . This book was released on 1965 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report assembles and correlates information on the effects of electrochemical metal-removal (ECMR) processes on mechanical properties. Of special interest and concern are the effects of ECMR on fatigue strength. The report covers four electrochemical metal-removal processes: electrochemical machining (ECM), electrolytic grinding (EG), electrochemical milling, and electropolishing. General characteristics and applications of the four methods are presented and discussed; special emphasis is placed on ECM. The ECMR processes are especially useful in shaping high-strength and difficult-to-machine metals and alloys, as well as in shaping parts with unusual, complex, or fragile characteristics. (Author).

Book Department of Defense Refractory Metals Sheet Rolling Program

Download or read book Department of Defense Refractory Metals Sheet Rolling Program written by D. J. Maykuth and published by . This book was released on 1965 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report is the third of a series which will periodically summarize the status of the various contracts involved in the Department of Defense Refractory Metals Sheet Rolling Program. Under this program, selected candidate materials are being carried through one or more of the following consecutive phases: Phase I, development of a sheet-production practice; Phase II, establishment of minimum design data; and Phase III, evaluation of sheetfabrication characteristics. To the present time, 13 contracts have been funded or planned in support of the Phase I, II, and III activities. This report summarizes the status of each of these individual contracts as of November 1, 1964. The first section describes the overall program of the Department of Defense Refractory Metals Sheet Rolling Program. Following, in the order of their discussions, are sections dealing with fabricable molybdenum alloys, unalloyed tungsten, columbium alloys, and tantalum alloys. (Author).

Book Oxidation of Nickel and Cobalt base Superalloys

Download or read book Oxidation of Nickel and Cobalt base Superalloys written by Carl H. Lund and published by . This book was released on 1965 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents information dealing with the oxidation of nickel- and cobalt-base superalloys. All of the superalloys will oxidize at high temperatures when oxygen is present in the enveloping atmosphere. The rate of oxidation depends upon alloy composition, temperature, oxygen concentration, oxides formed, diffusion rates of the metals in both base metal and oxide, diffusion rate of oxygen in the oxide, solubility of oxygen in the matrix, and a host of other variables. The effects of oxidation can be beneficial or they can be harmful. The first section of this report deals with the fundamentals of the oxidation of Ni-Cr and Co-Cr alloys. Subsequent sections discuss general surface oxidation, intergranular oxidation, other subsurface oxidation, and the effect of stress on the rate of oxidation. Numerous specific alloys are mentioned in the report; as an aid to the reader, the appendix contains an alloy index of the alloys mentioned in the report along with the compositions of the alloys, and the pages on which mention of the alloys is made.

Book Metal Deformation Processing

Download or read book Metal Deformation Processing written by F. W. Boulger and published by . This book was released on 1967 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Premium quality Aluminum Castings

Download or read book Premium quality Aluminum Castings written by K. R. Grube and published by . This book was released on 1965 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Premium-quality castings are those which are guaranteed to show a specified high level of mechanical properties. The properties currently being achieved represent significant improvements over those which can be achieved in conventional aluminum-alloy castings and approach the properties currently obtainable in wrought aluminum alloys. These property advances are largely the result of improved casting technique and design. These castings are gradually finding acceptance and usage in aerospace applications, thanks to integrated efforts between the casting producers and their customers. (Author).

Book Fiber reinforced Metal matrix Composites

Download or read book Fiber reinforced Metal matrix Composites written by Curtis Maitland Jackson and published by . This book was released on 1967 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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).

Book Forming of Titanium and Titanium Alloys

Download or read book Forming of Titanium and Titanium Alloys written by D. E. Strohecker and published by . This book was released on 1967 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
