    Abstract
    The precipitation of the omega phase in quenched titanium-vanadium alloys of 15% to 25% vanadium was investigated by x-ray analysis and resistivity measurements. The omega phase precipitation was found to be controlled by an enhanced diffusion mechanism which was closely linked to a pre-precipitation process occurring in these alloys. This pre-precipitation process is believed to be the cause of the negative temperature coefficient of resistance observed in these alloys below 0°C. Contrary to the results of previous investigations, no martensitic transformation of the beta phase to the omega phase was observed at low temperatures.
