A method for forming a dispersion-strengthened material containing nanoparticles that are uniformly dispersed in a matrix phase. The method includes adding nanoparticles and a molten material to a container to form a pool within the container and rotating the container to create a convection vortex in the pool. The convection vortex is sufficient to cause the nanoparticles to be incorporated into the molten material so as to yield a molten composite material, and further causes the molten composite material to be ejected from the container. The molten composite material is then cooled to form a solid composite body comprising a uniform dispersion of the nanoparticles.

Process for producing materials reinforced with nanoparticles and articles formed thereby

A method of assembling a gas turbine engine includes coupling an annular exhaust duct to the gas turbine engine, coupling a plurality of chevrons to the annular exhaust duct, and coupling a chevron actuation system to the annular exhaust duct such that selective operation of the chevron actuation system repositions the plurality of chevrons to adjust an amount convergence of the annular exhaust duct.

A metal nut for clamping a metal or nonmetal x-ray target to a metal anode stem or a rotating anode x-ray tube. The nut body is basically circular and has an axial threaded hole. The body has an axially extending cylindrical portion that is contiguous with a generally convex portion on one side of the cylindrical portion and is concave on the other side. The concavity is surrounded by an annular land for transmitting compressive force to the target. A cross-section of the nut simulates a beam that is thickest axially adjacent the central threaded hole and decreases in thickness symmetrically radially away from the center so it will flex when tightened at room temperature and have residual force stored when hot to compensate the metals for thermal creep.
