A method for atomizing a titanium-based material to particulates in a controlled atmosphere. In the method, titanium is skull melted in a crucible. The molten titanium-based material is transferred to a heated tundish. The molten titanium-based material may be stabilized in the heated tundish and then formed into a free-falling stream. The free-falling stream of the molten titanium-based material is impinged with an inert gas jet to atomize the molten titanium-based material. The method also includes cooling the atomized titanium-based material, and collecting the cooled atomized titanium-based material.

Method for atomizing a titanium-based material

A system and method for atomizing a titanium-based material to particulates in a controlled atmosphere. The system includes a crucible for skull melting a titanium-based material. The molten titanium-based material is transferred to a tundish for receiving the molten titanium-based material. The tundish has a bottom portion with an aperture formed therein and is heated. A molten metal nozzle for forming the molten titanium-based material into a free-falling stream exiting from the tundish is provided, the molten metal nozzle being coaxially aligned with the aperture of the tundish. A baffle may be disposed in the tundish for stabilizing the free-falling stream of the molten titanium-based material. The molten titanium-based material is atomized by impinging the free-falling stream of the molten titanium-based material with an inert gas jet issuing from a gas nozzle. The system also includes a device for cooling the atomized titanium-based material, and a device for collecting the cooled atomized titanium-based material.

System and method for atomizing a titanium-based material

A method for producing iron-silicon alloy articles having an improved combination of hot workability and electrical properties; the method comprises taking a molten alloy mass of an iron-silicon alloy from which the article is to be made and gas atomizing it to form alloy particles which are quickly cooled to solidification temperature. These alloy particles are then hot isostatically pressed to form a substantially fully dense article. The fully dense article is then hot rolled to sheet form suitable for example for use as laminates in the manufacture of transformer cores.
