Patent Number Title Of Patent Date Issued
5970307 Sintering method for tungsten-nickel-manganese type heavy alloy October 19, 1999
A sintering method for a W--Ni--Mn type heavy alloy, including controlling the deoxidization of tungsten and nickel under an inert atmosphere, changing to a hydrogen atmosphere at above a temperature at which manganese is deoxidized and simultaneously deoxidizing tungsten, nickel and
5956559 Irregular shape change of tungsten/matrix interface in tungsten based heavy alloys September 21, 1999
A method for producing an irregular tungsten/matrix interface in tungsten based heavy alloy is disclosed. The method involves a cyclic heat treatment and resintering at above liquidus temperature for tungsten heavy alloys consisting of 80 to 98 weight % tungsten and remainder of matrix
5956558 Fabrication method for tungsten heavy alloy September 21, 1999
A fabrication method for a tungsten heavy alloy includes first fabricating a green compact or a sintered body composed of tungsten and other elements except manganese, then putting manganese thereon, and sintering the tungsten heavy alloy with manganese manganese, whereby the formation o
