Tungsten alloys containing approximately 0.75 and 2.3 vol pct Zr0₂
were prepared by powder metallurgical methods from blends
of commercial
tungsten powder and ZrW₂ powder.
A heat treatment of the extruded rods
at 1800°C was found to produce a stable structure with a
dispersion of
Zr0₂ particles in the tungsten...
