Tungsen--nickel--cobalt alloy and method of producing same

Description

An improved tungsten alloy having a tungsten content of approximately 95 weight percent, a nickel content of about 3 weight percent, and the balance being cobalt of about 2 weight percent is described. A method for producing this tungsten--nickel--cobalt alloy is further described and comprises coating the tungsten particles with a nickel--cobalt alloy, pressing the coated particles into a compact shape, heating the compact in hydrogen to a temperature in the range of 14000C and holding at this elevated temperature for a period of about 2 hours, increasing this elevated temperature to about 15000C and holding for 1 hour at this temperature, cooling to about 12000C and replacing the hydrogen atmosphere with an inert argon atmosphere while maintaining this elevated temperature for a period of about 1/2 hour, and cooling the resulting alloy to room temperature in this argon atmosphere
