摘要： A turbine engine component may comprise a Ceramic Matrix Composite (CMC) structure including a plurality of nominally dense plies, wherein each of the plurality of the nominally dense plies are bonded by at least one of a Field Assisted Sintering Technique (FAST), a Spark Plasma Sintering (SPS), or a localized heating at a bonding interface. The turbine engine component may include an airfoil extending between a first platform and a second platform, wherein the airfoil, the first platform, and the second platform define the CMC structure.

摘要： An additively manufactured alloy component has a first portion formed of the alloy and having a first grain size, and a second portion formed of the alloy and having a second grain size smaller than the first grain size. In an embodiment, the alloy component is an alloy turbine disk, the first portion is a rim region of the alloy turbine disk, and the second portion is a hub region of the alloy turbine disk. The first and second grain sizes may be achieved by controllably varying the laser power and/or scan speed during additive manufacturing.

摘要： A method for heat treating metal alloy powder includes (a) introducing metal alloy powder to a chamber having a floor and a sidewall; (b) flowing a fluidizing gas through the floor and into the chamber to fluidize the metal alloy powder in the chamber; (c) flowing an additional gas through the sidewall into the chamber; and (d) heating the chamber to heat treat the metal alloy powder in the chamber. A system for heat treating metal alloy powder includes an inner chamber having a porous floor and a porous sidewall; an outer chamber, the inner chamber being inside of the outer chamber and defining an annular space between the outer chamber and the inner chamber, wherein the outer chamber and the inner chamber are inside a furnace; a source of fluidizing gas connected to the porous floor through the annular space; and a source of additional gas communicated with the porous sidewall through the annular space.

摘要： An embodiment of a method includes fabricating a first single crystal boule having a uniform composition and grain orientation. The first uniform single crystal boule is divided into a first plurality of layered shapes. The shapes of the first plurality are stacked with at least a second plurality of layered shapes along a first axis. The second plurality of layered shapes have at least one physical aspect differing from at least one corresponding physical aspect of the first plurality of layered shapes. The first plurality of layered shapes and at least the second plurality of layered shapes are joined via a field assisted sintering technique (FAST) to form a bulk component.

摘要： A method for processing a powder material includes feeding a powder material through an additive processing machine to deposit multiple layers of the powder material onto one another and using an energy beam to thermally fuse selected portions of the layers to one another with reference to data relating to a particular cross-section of an article being formed. The powder material has spherical metal particles and a spaced-apart distribution of ceramic nanoparticles attached to the surfaces of the particles. The ceramic nanoparticles form a dispersion of reinforcement through the formed article.
