摘要： A hollow component for gas turbine engine, for example an outlet guide vane, is assembled from a body having at recessed pocket formed therein, and an aerodynamic cover bonded over the pocket. Both the cover and the body are constructed from materials which are not readily fusion weldable. The cover is attached to the body by a solid state bonding process, for example friction stir welding. The hollow component may also be built up from multiple individual components which are bonded to each other by a solid state bonding process such as friction stir welding.

摘要： A method of making a fiber-reinforced component includes: providing a first composite member having a metal matrix with reinforcing fibers distributed therein; providing a second composite member having a metal matrix with reinforcing fibers distributed therein; and joining the first member to the second member by friction stir welding along a predetermined joint path, such that an average volume fraction of the reinforcing fibers within the joint path is substantially the same as an average volume fraction thereof in the composite members before joining. A fiber-reinforced component includes: first and second members each having a metal matrix with reinforcing fibers distributed therein. The first member is bonded to the second member by a solid state bond along a predetermined joint path, such that an average volume fraction of the reinforcing fibers within the joint path is substantially the same as an average volume fraction thereof in remainder of the members.

摘要： A method for welding iron-based or nickel-based superalloy assemblies into a unitary article. First, the assemblies are heated in an air atmosphere, at a rate suitable to minimize geometric distortion, to a temperature in the range of about 1400 F (760 C) to about 2000° F. (1090° C.) to form an oxide layer on the surface of the assemblies and optionally as a pre-weld solution heat treat. The temperature of the assemblies are then held in a range of about 1400 F (760 C) to about 2000° F. (1090° C.) for a time sufficient to form an oxide layer of sufficient thickness on the surface of the assemblies and optionally to solution the assemblies. The assemblies are then cooled to ambient temperature at a rate sufficient to avoid precipitation of unwanted metal phases at a rate sufficient to maintain dimensional stability. The oxide layer is then removed from at least the faying surfaces of the assemblies, but not from the face side of the assemblies. The faying surfaces of the assemblies are then cleaned. The assemblies are then welded using a GTA welding procedure to form a unitary article. The article is then resolutioned at an appropriate temperature for an appropriate period of time, both of which are dependent on the type of superalloy(s) that is present in the welded article and the desired properties. The article is then optionally age heat treated at an appropriate temperature for an appropriate period of time, both of which are dependent on the type of superalloy(s) that is present in the welded unitary article.
摘要翻译：将铁基或镍基超级合金组件焊接成整体制品的方法。首先，将组件以适合于将几何变形最小化的速率在空气气氛中加热至约1400°F（760℃）至约2000°F（1090℃）的温度以形成氧化物在组件的表面上并且可选地作为预焊接溶液热处理。然后将组件的温度保持在约1400°F（760℃）至约2000°F（1090℃）的范围内足以在组件的表面上形成足够厚度的氧化物层的时间，以及可选地解决组件。然后将组件以足以避免不必要的金属相以足以维持尺寸稳定性的速率沉淀的速率冷却至环境温度。然后从组件的至少拼接表面除去氧化层，而不是从组件的表面侧去除氧化层。然后清洁组件的接合表面。然后使用GTA焊接程序焊接组件以形成整体制品。然后将物品在合适的温度下分解合适的时间，这两个时间段都取决于焊接制品中存在的超级合金的类型和所需的性能。然后将制品任意地在合适的温度下对其进行老化热处理适当的时间，这两个时间取决于焊接的整体制品中存在的超级合金的类型。
