Abstract (en)
A method of making a reinforced refractory metal composite. A composition is prepared which comprises about 50 to about 99.9% by volume of niobium and about 0.1 to about 50% by volume of a particulate or fibrous dispersoid. The particulate dispersoid is an oxide, carbide, or boride of titanium, hafnium, zirconium, silicon, or a mixture thereof. The fibrous dispersoid is a carbide or boride of titanium, hafnium, zirconium, silicon, or a mixture thereof. The composition is mechanically alloyed in vacuum or in an inert atmosphere if a particulate dispersed is used It is then hot pressed at a temperature greater than at 1000 DEG C and a pressure greater than 70 atmospheres, and is extruded to form a shape. A fiber reinforced refractory metal composite made by this method is also described.
