摘要： Ni base superalloys containing relatively large amounts of Al and/or Ti are known to be difficult to weld satisfactorily. As the Al and Ti content of the superalloy is increased to improve the strength, the weldability of the component is drastically reduced. It is concluded herein that reducing the γ' phase improves weldability. A stepwise, controlled heating and cooling process is described to be used in cooperation with a welding process to reduce the γ' present and thereby improve weldability.

摘要： A turbine engine component, such as a turbine blade or vane, with complex internal features can be cast using a core having a first region with normal resolution features and a second region with high resolution features. The core can be formed from a single structure. Alternatively, the first region can be defined by a first ceramic core piece, which can be formed by any conventional process, such as by injection molding or transfer molding. The second region can be defined by a second ceramic core piece formed separately by a method effective to produce high resolution features, such as tomo lithographic molding. The first core piece and the second core piece can be joined by interlocking engagement, such as by male and female dovetails. The high resolution features can be effective to produce high efficiency internal cooling features in the cast component

摘要： A superalloy substrate, such as a turbine blade or vane, is fabricated or repaired by laser beam welding to clad one or more layers on the substrate. Laser optical energy is transferred to the welding filler material and underlying substrate to assure filler melting and adequate substrate surface wetting for good fusion. Energy transfer is maintained below a level that jeopardizes substrate thermal degradation. Optical energy transfer to the filler and substrate is maintained uniformly as the laser beam and substrate are moved relative to each other along a translation path by varying the energy transfer rate to compensate for localized substrate topology variations.
摘要翻译：通过激光束焊接来制造或修复超级合金基底，例如涡轮机叶片或叶片，以在基底上包覆一个或多个层。激光光学能量被转移到焊接填充材料和下面的基底上以确保填充物熔化并且适当的基底表面润湿以实现良好的熔合。能量传输保持在低于基材热降解水平的水平以下。当激光束和衬底沿着平移路径相对于彼此移动时，通过改变能量传输速率来补偿局部衬底拓扑变化，向填充物和衬底的光能传输保持均匀。

摘要： A removed damaged portion of a fully consolidated turbine engine component is replaced with a powder coupon that includes powder particles that are at most partially sintered or are bonded together with a binder. A bonding agent is applied to the component and/or the powder coupon. The powder coupon is then positioned over the component and heat is applied to fully sinter the powder particles, thus causing the powder coupon to shrink onto the component. The heat also activates the bonding agent to bond the shrunken powder coupon to the component, but the heat does not sinter the material forming the fully consolidated component.

摘要： Superalloy components (20), such as service-degraded turbine blades and vanes, are clad by laser beam welding. The welding/cladding path, including cladding application profile, is determined by prior, preferably real time, non-contact 3D dimensional scanning of the component (20) and comparison of the acquired dimensional scan data with specification dimensional data for the component (20). A welding path (21) for cladding the scanned component (20) to conform its dimensions to the specification dimensional data is determined. The laser welding apparatus (60), preferably in cooperation with a cladding filler material distribution apparatus (70), executes the welding path (21) to apply the desired cladding profile. In some embodiments a post-weld non-contact 3D dimensional scan of the welded component is performed and the post- weld scan dimensional data are compared with the specification dimensional data. Preferably the welding path (21)and/or cladding profile application are modified in a feedback loop with the pre- and/or post- welding 3D dimensional scanning.

摘要： An apparatus (10) and method for evaluating an effect of a surface presentation angle (A). The apparatus supports a plurality of samples (12) separated by support plates (18) between end plates (22) in a shish kebab arrangement. A groove (34) is formed on each side of each support plate for receiving an edge of each respective sample at a different angle relative to an axis of impingement (32). A clamping mechanism (20) holds the end plates, support plates and samples together in the fixed orientation exposing each sample surface at a different presentation angle, yet at the same distance from a process end effector (30). The sample impingement surfaces are exposed to the process, and the effect of the different surface presentation angles is determined from the samples. Process variables to counter the effects of surface presentation angle may be identified and controlled.

摘要： A method of additively manufacturing or repairing a superalloy component utilizing at least a double solution heat treatment and sub-cooling is presented. The at least double solution heat treatment includes heating the tip of a superalloy component to a first temperature for a first time period then allowing the tip to cool to ambient, then heating the tip to a second temperature for a second time period then allowing the tip to cool to ambient. An additive manufacture or laser braze repair process of the tip is commenced by depositing a layer of braze material on an end surface of the tip at a temperature less than the melting temperature of the composition of the base material of the component. Sub-cooling of the deposited layer is performed directly following the laser braze repair. A system of additive manufacture or repair is also presented.

摘要： A cored filler wire (10) used in a laser metal deposition (LMD) process and method of using the same. The cored filler wire includes an outer shell (12) surrounding an inner filler material (14). The outer shell is formed from a first material, e.g., a nickel based alloy having a low gamma prime content. The inner filler comprises at least a second material, e.g., a nickel based superalloy powder material comprising a gamma prime content higher than the first material. Upon laser processing, via LMD, and subsequent solidification, the resulting build-up layer (18) formed from the processed cored filler wire comprises an identical or near identical chemical composition to that of the underlying base material (5) or component being repaired.
