Joining of Titanium
Author: Robert Edward MonroePublisher:
ISBN:
Category : Adhesives
Languages : en
Pages : 86
Book Description
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).

Summary of Contractor Results in Support of the Refractory Metals Sheet Rolling Program
Author: D. J. MaykuthPublisher:
ISBN:
Category : Fusion zone (Welding)
Languages : en
Pages : 108
Book Description
This report summarizes the achievements on fourteen programs that were conducted in support of the Metals Sheet Rolling Program. These included programs for developing practices to produce large sheets from two grades of unalloyed tungsten (via powder metallurgy and arc melting, respectively), as well as for the Mo-0.5Ti, Mo-0.5Ti-0.1Zr-0.03C (TZM), Cb-10W-1Zr-0.1C (D-43), Cb-10W-2.5Zr (Cb-752), and Ta-30Cb-7.5V alloys. In addition, pilot sheet-rolling programs were also carried out for the Cb-27Ta-10W-1Zr (FS-85), Cb-5Mo-5V-1Zr (B-66), Ta-7W-3Re (GE-473), and Ta-9.6W-2.4Hf-0.01C (T-222) compositions.

Author: F. C. HoldenA Primer on Soviet Superalloys
Author: J. Prock (Jr.)Publisher:
ISBN:
Category : Cobalt-nickel alloys
Languages : en
Pages : 64
Book Description
Soviet nickel-base and cobalt-base alloys for high-temperature operation are described. Wrought and cast turbine blading alloys are included, as well as oxidation-resistant sheet alloys. Mechanical and physical properties of each alloy are assembled, and a detailed list of references is presented. Where possible, the specific applications are noted. It was concluded that the Soviets have made significant contributions to superalloy development, having successfully circumvented a shortage of cobalt and molybdenum. (Author).
Chromium and Chromium Alloys
Author: D. J. MaykuthPublisher:
ISBN:
Category : Chromium
Languages : en
Pages : 130
Book Description
Various alloying additions have been discovered which render unalloyed chromium much less susceptible to low-temperature embrittlement as well as to nitridation in air at elevated temperatures. These include additions of the Group IIIA metals, magnesia, and carbides based on the Groups IVA and VA metals. Of these additions, only the carbides contribute significantly to the hot strengthening of chromium. The combination of selected carbides and solid-solution-strengthening elements such as tungsten, molybdenum, and/or tantalum, has resulted in experimental alloys which retain useful strengths at temperatures through 1316 C (2400 F). These high strengths are achieved at some sacrifice in the low-temperature ductility of chromium. Also, despite the improvements afforded in the oxidation and nitridation resistance of chromium through alloying, no alloys are available which are capable of service in long-time exposures in air above 982 C (1800 F) without suffering some property degradation.
