Mechanical Properties and High Temperature Deformation of Beta Titanium Alloys
Because of its excellent environmental resistance and cold-working capacity, beta titanium alloy Ti-15-3 has attracted more and more attention in aerospace manufacture industry. Another beta titanium alloy, Ti-29-13, has been recently developed for biomedical implant materials. The mechanical properties of three alloys including two β and one α+β are presented, particularly the characteristic of β alloy differing from that of α+β alloy. The high temperature deformation behaviors of two alloys are also presented. Excellent formability of Ti-15-3 highlights the metal sheet application in commercial and military airplane. Band structure in Ti-29-13 has been found. Thermalmechanical processing is carried out to reduce the band structure and improve the elongation.
