ABSTRACT:
Disclosed is a Ti alloy which can provide a high strength and achieve a high ductility only with an annealing treatment without being provided a solution treating and aging process by adding O, C and Fe in a good balance to a basic chemical composition system such as Al and V in a Ti-6Al-4V alloy or a chemical composition system obtained by increasing Al in the above chemical component system and further adding thereto a suitable amount of N according to the addition amounts of Al, O, C, and Fe.
