Current And Future Trends In The Utilization Of Titanium

This report has been prepared almost entirely from information available in trade magazines, newspapers, and press releases. The report points out trends in the application of titanium and its alloys, and provides some statistics on the current availability of titanium sponge, ingot, and mill product. A final section points out some of the factors which will be involved in the future supply-demand situation, and provides a preliminary assessment of that situation. In the appendix, price data as well as detailed data on the availability of specific mill forms is given. (Author).

The Memorandum discusses the current situation on the inclusion of fracture-toughness testing requirements in specifications for high-strength steels used for military applications. The Memorandum was prepared at the request of The Technical Cooperation Program (TTCP), and contains information from Canadian and British members of that program, as well as U.S. information. Military applications discussed include missile motor cases, aircraft landing gear, gun tubes, armor plate, and hydrofoils. (Author).

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.

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).

This memorandum reviews nineteen papers dealing with melting and casting technology of particular interest to DMIC users. The papers were given at the International Metallurgy Conference on June 12-16, 1967 at New York City. These papers were broadly concerned with progress in vacuum-metallurgy technology internationally, materials in vacuum environment, vacuum-metallurgical processes, and vacuum equipment and instrumentation.
