The Influence of Chemistry and Various Fabrication Parameters on the Properties of Tungsten Heavy Metals.

Abstract

Extensive studies of the effects of various sintering parameters and many substituents on the mechanical properties of tungsten test samples produced by powder metallurgical methods have been completed. As final result of this work it can be stated that the influence of the sintering parameters is much more pronounced than that of the purity of the starting W powders, if they are in the normal range of a good high quality industrial product. For both absolute values and reproducibility of the mechanical properties, diviations from the optimum sintering cycle can do more harm than impurities in the W-powders. During production, therefore, control of the sintering process seems to pay off more than the purchase of extremely pure, and expensive, W powder. (Author)
