摘要： The invention relates to a method of producing elongate metal strands or fibres with a crucible, the method comprising the steps of; directing molten metal through a nozzle having a nozzle direction in a deposition direction at a regulated pressure difference between the inside and the outside of the crucible; depositing said molten metal from said nozzle on a rotating planar surface having an axis of rotation; entraining said molten metal in one plane via said rotating planar surface to form elongate metal strands, wherein said rotating surface is aligned at an alignment angle, to the deposition direction during the entraining of the molten metal; cooling said elongate metal strands to form solidified metal strands; and guiding said metal strands to collecting means to collect the solidified metal strands formed on the rotating planar surface.

摘要： A production method of particulate materials, through centrifugal atomization (CA) is disclosed. The method is suitable for obtaining fine spherical powders with exceptional morphological quality and extremely low content, or even absence of nonspherical-shape particles and internal voids. A appropriate cost effective method for industrial scale production of metal, alloy, intermetallic, metal matrix composite or metal like material powders in large batches is also disclosed. The atomization technique can be extended to other than the centrifugal atomization with rotating element techniques.

摘要： Provided is a group of rare-earth regenerator material particles having an average particle size of 0.01 to 3 mm, wherein the proportion of particles having a ratio of a long diameter to a short diameter of 2 or less is 90% or more by number, and the proportion of particles having a depressed portion having a length of 1/10 to ½ of a circumferential length on a particle surface is 30% or more by number. By forming the depressed portion on the surface of the regenerator material particles, it is possible to increase permeability of an operating medium gas and a contact surface area with the operating medium gas.

摘要： A method and device for producing shots are provided where the yield is improved. In a space (5) for forming molten drops, which space is surrounded by water (1) in a tank (20), by a cover (3) to cover an area surrounding a disc (2) that is located above the water and rotates, and by a tundish (4) that penetrates through the cover, a gas is discharged though an opening (6) that is formed in the cover and the film (9) of the water is formed on the inner surface of the cover. The molten metal (10) flows through the hole (11) in the bottom of the tundish to be supplied onto the rotating disc. The molten drops are formed by centrifugal force from the molten metal that has been supplied to the disc. Then the molten drops are caused to collide with the film of the water on the inner surface of the cover, to be divided into the droplets that are smaller than the molten drops. The droplets are cooled and solidified.

摘要： Embodiments of a method for producing powder mixtures having uniform dispersion of ceramic particles within larger superalloy particles are provided, as are embodiments of superalloy powder mixtures. In one embodiment, the method includes producing an initial powder mixture comprising ceramic particles mixed with superalloy mother particles having an average diameter larger than the average diameter of the ceramic particles. The initial powder mixture is formed into a consumable solid body. At least a portion of the consumable solid body is gradually melted, while the consumable solid body is rotated at a rate of speed sufficient to cast-off a uniformly dispersed powder mixture in which the ceramic particles are embedded within the superalloy mother particles.
