Tungsten-nickel-cobalt alloy and method of producing same |
摘要 |
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 said tungsten-nickel-cobalt alloy is further described and comprises (a) coating the tungsten particles with a nickel-cobalt alloy, (b) pressing the coated particles into a compact shape, (c) heating said compact in hydrogen to a temperature in the range of 1400 DEG C and holding at this elevated temperature for a period of about 2 hours, (d) increasing this elevated temperature to about 1500 DEG C and holding for 1 hour at this temperature, (e) cooling to about 1200 DEG C and replacing the hydrogen atmosphere with an inert argon atmosphere while maintaining this elevated temperature for a period of about 1/2 hour, and (f) cooling the resulting alloy to room temperature in this argon atmosphere.
