    • PURPOSE: A manufacturing method of titanium alloy for super-plastic forming is provided to enhance the super plasticity characteristic of the titanium alloy for super-plastic forming by using titanium alloy including aluminium(Al) and vanadium(V). CONSTITUTION: The Ti alloy is prepared(ST10). The Ti alloy is rolled at the temperature of 775°C~875°C with the amount of deformation more than 0.9(ST20). The Ti alloy is rolled in the deformation rate of 0.0007/sec~0.13/sec. The Ti alloy is rolled at the temperature of 775°C~825°C and in the deformation rate of 0.07/sec~0.13/sec and the mount of 1.4 or greater. The Ti alloy is rolled at the temperature of 775°C~825°C and in the deformation rate of 0.007/sec~0.013/sec and the mount of 1.0 or greater. The Ti alloy is rolled at the temperature of 775°C~825°C and in the deformation rate of 0.0007/sec~0.0013/sec and the mount of 1.0 or greater. The Ti alloy is rolled at the temperature of 825°C~875°C and in the deformation rate of 0.07/sec~0.13/sec and the mount of 1.8 or greater. The Ti alloy is rolled at the temperature of 825°C~875°C and in the deformation rate of 0.007/sec~0.013/sec and the mount of 1.8 or greater. The Ti alloy is rolled at the temperature of 825°C~875°C and in the deformation rate of 0.0007/sec~0.0013/sec and the mount of 1.8 or greater. The Ti alloy includes aluminium and vanadium.
