Document Type and Number:
WIPO Patent Application WO/2023/128355
Kind Code:
A1
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 15wt% and ferrochrome in an amount of less than 4wt%.
