Abstract: A method for manufacturing a high-strength titanium alloy by using ferrochrome, and a high-strength titanium alloy are disclosed. The method for manufacturing a high-strength titanium alloy, according to the present invention, comprises the steps of adding ferrochrome, which comprises Cr, Fe, Si and C, to pure Ti, melting and cooling same so as to form a titanium alloy base material, and then hot forming the formed titanium alloy base material. The ferrochrome is added in an amount of less than 4 wt %.

Abstract: Disclosed are a high-strength, high-formability titanium alloy using molybdenum and ferrochrome and a manufacturing method therefor. In the titanium alloy manufacturing method according to the present invention, a titanium alloy base material is formed by adding ferrochrome including Cr, Fe, Si and C to an alloy or mixture of Ti and Mo, dissolving and cooling same to form a titanium alloy base material, and then hot molding the formed titanium alloy base material. At this time, addition is made of Mo in an amount of 1 to 15 wt % and ferrochrome in an amount of less than 4 wt %.
