Abstract
A near-&bgr; or &bgr; titanium alloy having high strength, high ductility, and high toughness which is capable of coil rolling at a high temperature and recoiling for high productivity, and a process for producing said titanium alloy. The titanium alloy contains not more than 1.0% (excluding 0%) of Si alone or in combination with not more than 10% of Sn. The process comprises heating a &bgr; alloy or near-&bgr; alloy containing not more than 1.0% (excluding 0%) of Si alone or in combination with not more than 10% of Sn and subjecting said alloy to plastic deformation while keeping silicides solved in it at a temperature above the &bgr;-transus, so that silicides precipitate in the form of fine particles, with recrystallization suppressed. The resulting titanium alloy is good in workability and has high strength after aging treatment.
