    摘要： A production method for a titanium alloy member includes preparing a titanium alloy material for sintering as a raw material of a sintered body; nitriding the titanium alloy material for sintering, thereby forming a nitrogen compound layer and/or a nitrogen solid solution layer in a surface layer of the titanium alloy material for sintering and yielding a nitrogen-containing titanium alloy material for sintering; mixing the titanium alloy material for sintering and the nitrogen-containing titanium alloy material for sintering, thereby yielding a titanium alloy material for sintering mixed with nitrogen-containing titanium alloy material; sintering the titanium alloy material for sintering mixed with nitrogen-containing titanium alloy material, thereby bonding the material each other and dispersing nitrogen contained in the nitrogen-containing titanium alloy material for sintering in a condition in which nitrogen is uniformly dispersed into an entire inner portion of the sintered body by solid solution.

    摘要： A titanium matrix composite laminate (42) includes alternating layers of a titanium matrix foil (12) and a fiber mat (14). The titanium matrix foil (12) is formed from a super alpha titanium alloy having a beta phase stabilizer equivalency of at least thirteen. The beta phase stabilizer is selected from the elements molybdenum, vanadium, niobium, tantalum, halfnium, tungsten or some combination thereof. The fiber mat (14) is formed of silicon carbide (SiC) and has a carbon coating. Once a layup (16) of the alternating layers is formed, it is placed in a mold (22). Heat and pressure are then applied in a step called consolidation (40). The result is a titanium matrix composite laminate (42).

    摘要： Fiber-reinforced titanium alloy and intermetallic matrix composites having improved stability and tensile strength properties at elevated temperatures. The base reinforced fibers are pre-coated with a tailorable tri-layer coating, such as Ti--TiN--Ti. Preferably the TiN layer is graded so as to have metal-rich outer surfaces, such as titanium-rich TiN, providing excellent bonding affinity for the base titanium layer, bonded to the surface of the fibers, such as silicon carbide, and for the outer titanium layer, bonded to the titanium aluminum matrix, and a compound core, such as stoichiometric TiN, providing a stable interfacial barrier against chemical reactions, whereby the tensile strength and resistance to cracking of the composite is preserved even at elevated temperatures of 900.degree. C. or higher.

    摘要： A method for fabricating a titanium aluminide composite structure consisting of a filamentary material selected from the group consisting of silicon carbide, silicon carbide-coated boron, boron carbide-coated boron, titanium boride-coated silicon carbide and silicon-coated silicon carbide, embedded in an alpha-2 titanium aluminide metal matrix, which comprises the steps of providing a beta-stabilized Ti.sub.3 Al foil containing a sacrificial quantity of beta stabilizer element in excess of the desired quantity of beta stabilizer, fabricating a preform consisting of alternating layers of foil and a plurality of at least one of the aforementioned filamentary materials, and applying heat and pressure to consolidate the preform. In another embodiment of the invention, the beta-stabilized Ti.sub.3 Al foil is coated on at least one side with a thin layer of sacrificial beta stabilizer. The composite structure fabricated using the method of this invention is characterized by its lack of a denuded zone and absence of fabrication cracking.
