Abstract

"The purpose of this research was to investigate the possibility of producing the multicarbides of tungsten and titanium from a tungsten oxide-titanium hydride-carbon mixture. It appears to be worthwhile to carry out the reduction, carburization, and pre-alloying in one process, i.e. reducing tungsten oxide with the dissociated hydrogen from titanium hydride and the added carbon; then carburizing the reduced tungsten metal and dissociated titanium metal; at last, pre-alloying the mixture of TiC and WC. The replacement of titanium hydride with titanium oxide seems to be more direct, simple, and economical process; but the difficulty in the reduction of titanium oxide may cause trouble in the furnace design; due to the high temperature needed together with a controlled atmosphere. The problem was attacked by considering the chemical thermodynamics of the possible reactions, and the mechanism of carburization. Different types of smelting furnaces and different batch compositions of the charge were tried. X-ray diffraction techniques and chemical analysis were used to determine the nature of the products"--Introduction, pages 2-3.
