Watertight, high-explosive forming facility, 25 feet in diameter and 15 feet deep, withstands repeated explosions of 10 pounds of TNT equivalent. The shell is fabricated of high strength steel and allows various structural elements to deform or move elastically and independently while retaining structural integrity.
Temperature dependence of mechanical properties of high strength alpha-phase titanium alloy containing aluminum
Thermal stability of high strength nickel alloys containing oxides prepared by powder metallurgy techniques
Safety design for high strength low toughness materials assumed to have hidden flaws, formulating stress intensity factor for fracture mechanics
Aluminum and magnesium composite sheet laminates reinforced with low density, high strength modular filament sheets are produced by diffusion bonding and explosive bonding. Both processes are accomplished in normal atmosphere and require no special tooling or cleaning other than wire brushing the metal surfaces just prior to laminating.
High strength abrasive resistant flame resistant flexible impregnated nickel-chromium fabric for space suits
Crack initiation phenomena associated with stress corrosion in high strength aluminum alloys
Stress corrosion cracking resistance testing of high strength weldable aluminum alloys including residual stresses
Because of such characteristics as high strength and long-term biocompatability, aerospace carbonaceous materials may be used as surgical implants to correct pathological conditions in the body resulting from disease or injury. Examples of possible medical uses include bone replacement, implantation splints and circulatory bypass implants.
Series of elements connected by idle rollers and two tapes /one for extension and one for retraction/ are used in the fabrication of a telescoping boom. The boom has high strength and rigidity which will allow a gravity dump at any point in the extension cycle.
Because introduction of hydrogen during bright-cadmium electroplating of high strength steels causes hydrogen-stress cracking, a program was undertaken to evaluate various processes and materials. Report describes effectiveness of inhibitors for reducing hydrogen absorption by steels.
Explosive bonding process produces sheet composites of aluminum alloy reinforced by high-strength stainless steel wires. The bonds are excellent metallurgically, no external heat is required, various metals can be bonded, and the process is inexpensive.
Stress corrosion cracking of high strength aluminum alloys investigated by electrochemical, mechanical, and electron microscopic techniques
Crack toughness characteristics of high strength alloys for use in heavy sections of supersonic aircraft
Hydrogen embrittlement and stress cracking studied on 14 selected high strength alloys
Mechanical property data on sheet and plate of high strength aluminum alloys
High temperature magnetic analysis of metallurgical structure of high strength steels and composites, including phase transformation and matrix grain structure
Wrought aluminum alloys provide high-strength substitute in the damaged area of aluminum castings. The segment can either be welded to the cast alloy or built in with a heat-treatable welding rod.
