摘要： An Fe—Ni—Cr alloy formulated to contain a strengthening phase that is able to maintain a fine grain structure during forging and high temperature processing of the alloy. The alloy contains a sufficient amount of titanium, zirconium, carbon and nitrogen so that fine titanium and zirconium carbonitride precipitates formed thereby are near their solubility limit in the alloy when molten. In the production of an article from such an alloy by thermomechanical processing, a dispersion of the fine titanium and zirconium carbonitride precipitates form during solidification of the melt and remain present during subsequent elevated processing steps to prohibit austenitic grain growth.

摘要： A method and portable device for modifying or coating a surface of turbine components in the field includes an ESD torch electrically connected with ESD equipment. The ESD torch includes an inert gas source, vibration source, and electrode disk of conductive material. The electrode disk is disposed within the ESD torch, shielded by an inert gas and coupled with the vibration source. The electrode disk is rolled over the surface, which actuates the electrode disk and deposits the conductive material from the electrode disk onto the surface of the workpiece to form the compositionally controlled protective coating. The compositionally controlled protective coating deposited by the electrode disk forms a metallurgical bond with the surface of the workpiece to prevent erosion of the workpiece.

摘要： A process of depositing layers of weld metal onto a ferrous NiMoV low alloy steel turbine component. During a deposition of a first layer of weld metal, low levels of amperage are used to prevent a dramatic increase in a level of hardness of a heat affected zone produced during the deposition of the first layer of weld metal. During a deposition of a second layer of weld metal, higher levels of amperage are used to temper the heat affected zone but not high enough to overtemper the HAZ.

摘要： A formed disc for use in a low pressure rotor has a rim made of a high alloy metal of between approximately 9% and 17% chromium. The rim can be annular in shape and slide onto the perimeter of an unformed disc for the two components to be fused together, thus fabricating a formed disc. Additionally, the rim can be split into a number of components and fused together on the perimeter of a rotor disc to form a complete rim. Further, an entire disc can be made out of the high alloy metal.

摘要： A low pressure steam turbine and generator low alloy steel disc rotors with extended useful life properties. A ring member of the disc rotor has disposed on it multiple weld layers of ferrous material, forming a weld region. The ring member is made of a low alloy ferrous metal alloy having less than about six weight percent alloying ingredients including chromium. The chromium content of the weld region increases overall from a portion of the weld region adjacent to the ring member to a portion of the weld region farthest from the ring member. This general increase is accomplished using weld metal of a single chromium concentration of between 9% and 17% chromium and varying the welding parameters.

摘要： A metal matrix composite lightweight compressor airfoil. The airfoil comprises a braided fabric embedded in a lightweight aluminum-lithium alloy. The airfoils are fabricated by forming a plurality of fiber tows by twisting filaments or fibers. The tows are then braided into a fabric. The fabric may be impregnated with an optional fugitive polymer that temporarily occupies interstices of the fabric to facilitate handling of the pre-formed braided fabric, but which is subsequently removed. The airfoil may then be formed as a MMC by one of two separate methods. In the first method, aluminum-lithium alloy is pressure augmented casting into a die that includes a preform of fabric impregnated with fugitive polymer. In a second method, a preform is formed using a tool and mandrel by impregnating fabric with aluminum-lithium alloy. Then aluminum-lithium alloy is pressure augmented cast into a die that includes the alloy-impregnated preform.
