Screw Form Rolling of Beta Type Titanium Alloy Preliminary Worked by Torsion
Beta type titanium alloys in a cold processability are light, have high strength, excellent corrosion resistance and the same level as Young's modulus of human bone. Therefore, beta type titanium alloys are used for plant facilities such as nuclear plants, architectural materials, aircraft, car, biomaterial, medical equipment, glasses and golf club head, etc. Microstructure and mechanical properties of beta type titanium alloys processed by rolling and heat treatment have been reported . Additionally, screw form rolling using beta type titanium alloys has also been reported . However, the development in those characteristics after the preliminary working by torsion has been unknown.
