- ‘Most alloying elements, such as chromium, columbium, copper, iron, manganese, molybdenum, tantalum, and vanadium stabilize the phase to the extent that a mixed - phase or an entirely phase alloy can persist down to room temperature.’

- ‘The gas tungsten arc welding process is used for the pure columbium and for the lower strength commercial alloys.’
