Method for producing titanium particles |
January 28, 1992 |
| Titanium is induction melted to produce a molten mass thereof and a water-cooled crucible having a nonoxidizing atmosphere and a bottom opening. The current to the coil used for induction melting is adjusted to produce a levitation effect on the molten mass in the crucible to prevent |

Method for atomizing titanium |
October 1, 1985 |
| A method for producing titanium particles suitable for powder metallurgy applications by atomizing a free-falling stream of molten titanium. Prior to atomization the molten titanium is maintained in a crucible lined with a solidified layer of titanium which separates the molten mass of t |

Method for the plasma-arc production of metal powder |
February 15, 1983 |
| A method for producing atomized metal particles, particularly of titanium-base alloys and superalloys, that are free from contamination by foreign material; this is achieved by providing a rod of the metal to be atomized and contacting an end portion of the rod with a plasma arc gas |

Method for producing powder metallurgy articles |
August 26, 1980 |
| This is a powder metallurgy method for producing fully dense compacted articles from powder charges of hydride-forming alloys, preferably titanium base alloys. The powder is hydrided, sealed in a collapsible container, heated to an elevated temperature and then hot compacted to produ |
