This memorandum deals with the use of liquid metals in advanced spacepower plants. The principal liquid-metal candidates for such applications are mercury, NaK, potassium, lithium, cesium, and sodium. These metals are used primarily as heat-transfer media and as working fluids at high temperatures. This memorandum identifies specific areas for molten metal use and discusses the materials, problems, and developments associated with their containment. (Author).

This memorandum reproduces thirteen lectures delivered at a Titanium Symposium held on March 28-29, 1966, at Hawthorne, California, under the auspices of the Norair Division of the Northrop Corporation. These lectures follow a logical sequence of topics including production aspects, metallurgy, manufacturing technology, and the design of titanium parts for aircraft and aerospace applications.

This memorandum briefly discusses the physical metallurgy, heat treatment, mechanical properties, stress-corrosion properties, and fabrication of the 9Ni-4Co-XC steels. This family of steels was developed specifically to meet the requirements of the aircraft and aerospace industries for materials possessing high strength and high toughness. By varying the composition and heat treatment, the 9Ni-4Co-xC steels can develop strengths in the 200 to 300 ksi tensile-strength range and reportedly possess high toughness. The lower carbon grades have excellent weldability, developing strength in the 180 to 200 ksi range with high toughness without the need for preheat or postweld-heat treatment. (Author).

The study surveys the present state of knowledge on the design of die sequences in closed-die forging with a view toward studying the feasibility of establishing an analytical procedure. The contents are comprised of (1) a review of present methods practiced in die-sequency design, (2) a review of factors involved in metal flow, and (3) examples of analytical work that might constitute the background for a more rational study of the closed-die-forging process.

Numerous industrial users were asked for their appraisal of vacuum-degassed steel. Their responses regarding the merits of this vacuum treatment were varied. The producers and users of large forgings reported fewer internal defects, improved toughness, and decreased processing time through shorter hydrogen relief treatments. Improved fatigue life in applications such as bearings was attributed to fewer and smaller nonmetallic inclusions in vacuum-degassed steel. The users of medium and small forgings reported only marginal improvement in properties and little or no change in rejection rates by nondestructive testing. Unfortunately, many of the users could not give a meaningful evaluation because they knew that frequently their suppliers filled orders with vacuum-degassed steels even though such treatment was not specified. Consequently, these users are unable to separate the air melted and the vacuum-degassed steels in their stock for comparison. A more comprehensive study of fully identified steels, steelmaking practice, degassing methods, material properties, and performance in service will be required before a satisfactory evaluation of the merits of vacuum-degassed steels can be made.

Weldability Of High Strength Aluminum Alloys written by Robert Melvin Evans and has been published by this book supported file pdf, txt, epub, kindle and other format this book has been release on 1966 with Aluminum alloys categories.
This memorandum describes the fusion-welding characteristics, mechanical properties, and stress-corrosion behavior of high-strength, weldable aluminum alloys. These are defined as alloys in which sound welds can be produced and in which at least 50 and 70 percent of the maximum base-metal strength can be retained in the as-welded and post-weld-treated conditions, respectively. Careful selection of joining method and filler metals as well as close control of joining-process parameters is necessary to produce high-strength aluminum weldments. Highest strengths and weld-joint efficiencies in high-strength weldable alloys are achieved with the use of postweld aging and/or mechanical treatments. The best combination of highest strengths and good welding characteristics is found in the 2000 and 7000 alloy series. As compared with the 2000 and 5000 alloy series, the 7000 alloy as a class suffer three major property disadvantages: (1) their tendency to be notch sensitive, (2) their tendency to exhibit low toughness at low temperatures, and (3) their much greater susceptibility to stress-corrosion cracking. Nonetheless, several relatively new 7000 series alloys have been developed which show reasonably good notch toughness to -423 F and which are considered competitive with the 2219 and 2014 alloys for cryogenic applications.
