Description

The paper is concerned with the problems concerning an increase in ductility of tungsten and its alloys produced by the method of powder metallurgy as well as concerning a decrease in susceptibility to brittle failure in terms of distribution of interstitial impurities along boundaries of structural elements using a method of Auger-electron spectroscopy. It is stated that rhenium introduced into tungsten through a homogeneous hardener weakens most effectively the effect of interstitial impurities
