Abstract
Process for preparing ductile refractory alloys based on tungsten, characterized in that it comprises homogeneously mixing in the form of powder from 0.03% to 0.4% and preferably from 0.1% to 0.15% by weight of thorium, from 0.003% to 0.03% and preferably from 0.004 to 0.019% by weight of carbon and up to 7%, and better still, from 1% to 7% by weight of rhenium, the rest, up to 100%, tungsten; subjecting this mixture to a pressure of the order of 3,500 Kgs/cm2 to form pearls, vitrifying them at a temperature of the order of 2350º C, for about 4 hours, to ensure the diffusion of the various constituents and form a solid solution of thorium and of rhenium in the tungsten, distributing the carbon between tungsten carbide and a solid solution of carbon in the tungsten; the pearls are then forged at a temperature of about 1850º C, to reduce their thickness between 13 and 7.5 mm; it is then rolled at a temperature of the order of 1.1550º C in sheets having a thickness of approximately 1 mm; During this manufacturing process the carbon precipitates in the form of finely dispersed thorium carbide.
