Alloy powder for producing tungsten alloys by means of powder metallurgy method

摘要

alloying powder for the manufacture of alloys, tungsten powder metallurgy method, consists of tungsten powders, alloy powder tih2 in quantities of up to 0.3% by weight of elemental s and powder in quantities of up to 0.3% by weight.the use of powders tih2 and y as alloying additives to tungsten alloy, that causes in the process of mechanical stopowania respond to such pollution alloy as coal and oxygen, causing formation of volatile compounds, which may be subsequently removed from the working chamber of the mill. this treatment allows to reduce the harmful elements, such as oxygen and carbon to 25%.
