Patent Number Title Of Patent Date Issued
5084091 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
4872927 Method for improving the microstructure of titanium alloy wrought products October 10, 1989
A method for improving the microstructure of wrought titanium alloy material which comprises the steps of hydrogenating the material at a temperature near or above the titanium-hydrogen eutectoid of C. (about to C.) to a hydrogen level of about 0.
4820360 Method for developing ultrafine microstructures in titanium alloy castings April 11, 1989
A method for improving the microstructure of cast titanium alloy articles which comprises the steps of hydrogenating the cast article at a temperature near or above the titanium-hydrogen eutectoid of C. (of about to C.) to a hydrogen level of about
4609526 Method for compacting alloy powder September 2, 1986
A method for producing high speed, tool and die steel articles from prealloyed powders. The method comprises placing particles of a prealloyed steel composition from which the article is to be made in a deformable container, heating the container and particles and then passing the heated
4544404 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
4374075 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
4219357 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
