摘要： A large-diameter tungsten-lanthana rod having an elongated grain structure substantially parallel to the longitudinal axis of the rod is described. The large diameter rod is produced by rolling at a temperature greater than 1400° C. and less than 1700° C. to achieve at least about a 40% reduction in cross-sectional area. The high strength of the longitudinally elongated grain structure is desirable for applications such as rocket nozzles.

摘要： A method of making a composite orifice having a tungsten core which is diffusion bonded to a molybdenum shell. Tungsten and molybdenum powders in contact with each other in a mold are isostatically pressed to form a pressed bonded composite part. The pressed, unsintered tungsten core portion of the part is then machined to the desired dimensions. The pressed composite part is then sintered to form a diffusion bonded composite orifice. The pressed and sintered molybdenum shell portion of the orifice may then be machined to the desired dimensions.

摘要： A method is disclosed for bonding liquid phase sintered metal powder parts of a tungsten alloy containing nickel. The method involves placing a sheet of copper based material between the parts at their adjoining surfaces to join the parts with the sheet covering essentially the entire area of the surfaces, heating the resulting assembly at a temperature sufficient to melt the copper based material without melting the parts, cooling the resulting heated assembly to room temperature, reheating the assembly at a temperature which is high enough to cause diffusion of the copper based material and the matrix alloying elements into one another without melting the parts, and cooling the resulting twice heated assembly.

摘要： The coating the tungsten powder particles with a ceramic barrier suppresses the leachability of tungsten in aqueous media. Preferably, the ceramic coating substantially encapsulates each particle of tungsten and has a thickness of at least about 30 nm and, more preferable, from about 200 nm to about 500 nm. Examples of ceramic coatings that may be used include, but are not limited to, aluminum oxide (alumina), aluminum oxyhydroxide (AlOOH), zirconium oxide (zirconia), cerium oxide (ceria), hafnium oxide (hafnia), and magnesium oxide (magnesia).
