Book Description
A summary is presented of the status of the Department of Defense Refractory Metals SheetRolling Program to accelerate the development of production techniques for high-quality, consistent sheet products from the refractory metals (Nb, Mo, Ta, and W) and their alloys. The program includes: (1) development of sheet production techniques, (2) establishment of minimum data re uired to evaluate mill production, (3) evaluation of fabrication characteristics of the sheet produced, and (4) establishment of design data. Contracts were awarded for the development of sheet production techniques for all four refractory metals. One contract was awarded for the evaluation of Mo alloy sheet fabrication characteristics.

ISBN:
Category : Heat resistant alloys
Languages : en
Pages : 48
Book Description
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).

Status Report No. 2 on Department of Defense Refractory Metals Sheet-rolling Program
Author: H. R. Ogden
Publisher:
ISBN:
Category : Heat resistant alloys
Languages : en
Pages : 54
Book Description
The Nb program is nearing completion of laboratory tory rolling studiory materials, *Heat resistant alloys, *Sheets, Niobium alloys, Molybdenum alloys, Tantalum alloys, Tungsten alloys, Titanium alloys, Zirconium alloys, Tungsten, Powder metallurgy, Electric arcs, Manufacturing methods, Mechanical proper ies, Forging, Heat treatment, Melting, Extrusion, Deformation, Hardness, Rolling mills, Processing. Identifiers: Floturning. The Nb program is nearing completion of laboratory tory rolling studies, and a single composition for larger scale rolling studies will be selected in the near future. In the Mo program, it has been shown that true hot forging of billets to sheet bar results in higher recrystallization temperatures of TZM and Mo-0.5Ti sheet than are obtained when normal forging temperatures are used. The Ta program is in the early stages of ingot production and primary breakdown fabrication of the Ta-30Nb-7.5V alloy. Three methods of fabricating W sheet are being investigated: rolling of powder-metallurgy billets, fabrication of arc-melted ingots, and floturning of cylindrical blanks. Properties obtained on both powdermetallurgy and arc-melted tungsten sheet compare very favorably. Evaluation of the formability of Mo-alloy sheet has been delayed until sheet is available from the production program. (Author).

A Discussion of the Physical Metallurgy of the 18 Per Cent Nickel Maraging Steels
Author: Albert M. Hall
Publisher:
ISBN:
Category : Nickel
Languages : en
Pages : 34
Book Description
Various aspects of the physical metallurgy of the 18 % nickel maraging steels are discussed in this report in the light of the knowledge which has thus far been accumulated on these steels. The 18 % nickel type of maraging steel was singled out for discussion because of its especially attractive combination of strength and fracture toughness, the comparative simplicity with which it can be hardened, and the relative ease with which it can be formed and joined. The highnickel maraging steels are considered to be outstanding members of a loose-knit family of agehardenable or precipitation-hardenable martensitic steels. Some comparisons and analogies are drawn among various members of this family with particular reference to the 18% nickel steels. (Author).

Book Description
This report supplements DMIC Report 152 which is a compilation of binary and ternary phase diagrams of columbium, molybdenum, tantalum, and tungsten. Forty new binary and 80 new ternary diagrams are included, some of these being revised versions of the previously published diagrams. Included with each binary diagram and with some ternary diagrams is a short discussion listing terminal solubilities and crystal struc tures of intermediate pahses. Many of the diagrams are tentative and are subject to revision as additional data become available. (Author).
