Abstract: A process of fabricating a corrosion and erosion resistant component. In one embodiment, the process entails applying one or more corrosion resistant materials onto a pre-formed, sacrificial core and then enclosing this first material and the core with a surrounding capsule. Any space within the capsule is then substantially filled with a second material, after which the capsule is sealed and treated to cause the second material to densify and to metallurgically bond to the first material. Thereafter, the core material and capsule are removed via chemical and/or mechanical processes to yield a component with a shape that approximates the space that existed between the capsule and the first material, and with an outer surface that reflects the shape of the outer surface of the core and the inner surface of the capsule.

Abstract: A metallic tube for transporting corrosive, abrasive, and erosive industrial flow streams. The tube has an outer tube material consisting of consolidated metallic powder bonded to an inner tube material consisting of a corrosion- or wear-resistant, weld- or spray-deposited material. The tube has a bend in it of at least about 45°, such as a U-bend, which would normally inhibit the weld- or spray-deposition of the corrosion- or wear-resistant inner tube material.

Abstract: Improved missile warhead body has three sections forming a tubular body closed by a cap section at one end thereof and having a center section comprising high density material inclusions of a selected size and weight which separate from the warhead when detonated and form shrapnel on the order of the size and weight of the high density material inclusions.

Abstract: A nickel-base superalloy compacted fully dense article, produced by a powder metallurgy technique from prealloyed powder, said article being characterized by the absence of thermal induced porosity when heated at temperatures of at least 2200.degree. F and exhibiting improved superplastic behavior during forming operations, such as forging.
