The occurrence of high-speed steel carbide-type eta phases in the Fe-Nb system
Description
The high-speed steel carbide-type eta phase claimed to exist in the Fe-Nb system at a composition Fe2Nb3 is an interstitial oxide, eta-Fe6Nb6O. It is obtained by heating Fe-Nb alloy powders in sealed and evacuated vitreous silica capsules at 10000C. A second eta phase with larger unit-cell dimensions is obtained by hydrogen treatment of Fe-Nb alloys at 1000-12000C; it is an interstitial nitride, eta-Fe3Nb3N, formed because even 'purified' hydrogen contains small concentrations of nitrogen. Examples of oxide formation by heat treatment of metals in vitreous silica and of nitride formation by heat treatment in hydrogen are not uncommon. (orig.)
