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).

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.

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).

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.

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.

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).
