摘要： A heat treatment technique may include heating an alloy component to a temperature above a transition temperature of the alloy or heating an alloy component to a temperature below the transition temperature of the alloy. The heat treatment technique further may include cooling a first portion of the alloy component at a first cooling rate, and cooling a second portion of the alloy component at a second cooling rate different than the first rate. The first cooling rate may result in formation of a plurality of first precipitate phase domains comprising a first average size in the first portion, and the second cooling rate may result in formation of a plurality of second precipitate phase domains comprising a second average size in the second portion. The average size of the first precipitate phase domains may be different than the average size of the second precipitate phase domains.

摘要： An improved method of forming a rotor includes the steps of hot isostatically pressing powdered metal to form disc-shaped hub sections. Each of the hub sections has a rim portion with a relatively large or coarse grain size to optimize high temperature creep properties. The central portion of each hub section has a relatively small or fine grain size to optimize tensile strength and reduce cycle fatigue at intermediate temperatures. Dispersion of any defects in the hub sections is promoted by plastically deforming the hub sections. Preformed blades are placed in an annular array between a pair of the hub sections and the hub sections are bonded together to interconnect the blades and hub sections.

摘要： An article may include a substrate that comprises a nickel alloy. The substrate may include a modified subsurface region and a bulk region. The modified subsurface region may include a first composition and the bulk region may include a second composition different than the first composition. The modified subsurface region may include at least one of a reactive element or a noble metal, and the modified subsurface region comprises a thickness of less than about 0.3 μm measured in a direction substantially normal to a surface of the substrate. The modified subsurface region may be formed by depositing a layer including at least one of the reactive element or the noble metal in a layer on a surface of the substrate and introducing the at least one of the reactive element or the noble metal into the modified subsurface region using ion bombardment.

摘要： The present invention generally relates to an external cylindrical or conic section shaped fixture which is tightly fit around the same shaped workpiece prior to expansion forming to a final dimension. During expansion forming, the external fixture is also deformed and is therefore designed for one-time use. The external cylindrical or conic section shaped fixture of the present invention is particularly useful for expansion forming of workpieces which contain brazed lap joints. The external fixture restrains, out-of-plane joint rotation and reduces the stress concentrations existing near the lap joints. Additionally, the external fixture provides additional load carrying capability to allow better load distribution during expansion forming. No change is required to the expansion forming machinery or the inner expander dies (jaws) with use of the present invention. Because the external fixture fits tightly over the workpiece, applying a compressive force when the inner expander jaws expand during the forming process, the bending moment on the brazed lap joints is significantly reduced.
摘要翻译：本发明一般涉及一种外部圆柱形或圆锥形截面形状的固定装置，其在膨胀形成至最终尺寸之前紧密地配合在同一成形工件周围。在膨胀成形期间，外部夹具也变形，因此被设计为一次性使用。本发明的外圆柱形或圆锥形截面固定装置特别适用于包含钎焊搭接接头的工件的膨胀成型。外部夹具限制，平面外关节旋转，并减少搭接点附近存在的应力集中。另外，外部夹具提供额外的承载能力，以在膨胀成形期间允许更好的载荷分布。膨胀成形机械或使用本发明的内部膨胀机模具（夹爪）不需要改变。由于外部固定装置紧紧地配合在工件上，所以在成形过程中内膨胀机夹爪膨胀时施加压缩力，钎焊搭接点上的弯矩明显减小。
