    摘要: An article made of constituent elements is prepared by furnishing at least one nonmetallic precursor compound, wherein all of the nonmetallic precursor compounds collectively contain the constituent elements. The constituent elements include a titanium-base metallic composition, boron present at a level greater than its room-temperature solid solubility limit, and, optionally, a stable-oxide-forming additive element present at a level greater than its room-temperature solid solubility limit. The precursor compounds are chemically reduced to produce a material comprising a titanium-base metallic composition having titanium boride particles therein, without melting the titanium-base metallic composition. The titanium-base metallic composition having the titanium boride particles therein is consolidated without melting.

    摘要: The rocket motor nozzle assembly of this invention includes a throat insert (22) and a carbon or silica protective eyelid (50). The throat insert has a carbon throat support (30) and a refractory metal shell (42, 44, 46). The shell is positioned radially inside the throat support to cover the inner surface of the throat support. The protective eyelid (50) covers a sufficient portion of the forward surface region (42) of the shell and the underlying converging portion of the throat support to protect these components against particle impingement. The protective eyelid extends sufficiently far forward along the converging/diverging pathway to cover and protect the forward face or edge of the throat insert and prevent the combustion gases from passing under the throat insert and reaching the radially outer surface of the throat insert. However, the protective eyelid leaves the throat surface region of the shell exposed to the converging/diverging pathway.

    摘要: A turbine blade squealer tip (38) includes an airfoil shaped tip cap (22) having a squealer tip wall (39) extending radially outwardly from and around the perimeter of the airfoil shaped tip cap (22) to define a radially outwardly open tip cavity (40). The tip wall has an inboard side (66) facing the interior of the cavity (40) and an outboard side (60) facing away from the cavity (40) and the tip cap (22) has an outer tip side on a bottom of the cavity (40). Thermal barrier coatings (48, 49) are disposed on the inboard and outboard sides (66, 60) of the squealer tip wall (39) and on the outer tip side of the tip cap (22). One embodiment provides the tip cap (22) with cooling holes (76) disposed therethrough to flow cooling air into the cavity (40). Radially outwardly shaped cooling holes are disposed through at least the pressure side of the airfoil immediately below the tip cap (22) for flowing cooling air radially outwardly along an outboard side (60) of the squealer tip wall (39).
