Summary:The present disclosure relates to a titanium alloy that includes about 5 to about 27 percent by weight cobalt and titanium and methods for manufacturing a metallic article comprising heating a mass of such titanium alloys to a thixoforming temperature, the thixoforming temperature being between a solidus temperature of the titanium alloy and a liquidus temperature of the titanium alloy, wherein a difference between the solidus temperature and the liquidus temperature of the titanium alloy is at least 100 C; forming the mass into the metallic article while the mass is at the thixoforming temperature; and maintaining the mass at the thixoforming temperature for at least 600 seconds prior to the forming the mass into the metallic article. La présente divulgation concerne un alliage de titane qui comprend de 5 à 27 % massique de cobalt et de titane et des méthodes de fabrication dun article métallique comprenant le chauffage dune masse de tels alliages de titane à une température de thixoformage, qui est entre une température « Solidus » et une température « Liquidus » de lalliage de titane, la différence entre la température Solidus et Liquidus de lalliage étant dau moins 100 ºC, la formation de la masse en article métallique lorsque le masse est à la température de thixoformage et le maintien de la masse à cette température pendant au moins 600 secondes avant sa formation en larticle métallique.
