Other elements added to improve characteristics include nickel, molybdenum, copper, titanium, aluminum, silicon, niobium , nitrogen, sulfur, and selenium.
A previous study of the columbite-tantalite series minerals indicated a similar change for tin, tantalum, niobium , and manganese.
The refractory metals include niobium (also known as columbium), tantalum, molybdenum, tungsten, and rhenium.
Certain strong carbide formers, notably niobium , titanium and vanadium, have effects on tempering out of proportion to their concentration.
This resource is potentially globally significant as a source of niobium and tantalum.
The proposed mine, which would dig for niobium , a rare metal, would be carved out of land near the Kahnesatake Mohawk reserve and the village of Oka.
However, titanium, niobium , and tantalum can influence mechanical properties still further by encouraging the formation of other similar types of precipitates.
The gyroscope rotors are covered with a layer of niobium , a metal that will superconduct when it is cooled by liquid helium.
The element always occurs with another chemical element, niobium .
Previous attempts to lower the switching temperature have incorporated low levels of elements such as tungsten, molybdenum, niobium and fluorine.
