Effect of the rate of cooling tungsten heavy alloys of the W–Ni–Fe type from the sintering temperature on the formation of their physico-mechanical properties

Abstract

The effect of the conditions of cooling after the liquid-phase sintering of tungsten heavy metals have been studied. It has been found that to attain a high ductility of the tungsten heavy metal, the rate of cooling from the sintering temperature should afford removal of the major part of hydrogen, which was dissolved in the alloy volume in the temperature range of the liquid phase existence.
