Deformation Behaviors

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.

Before And After

The deformation characteristics of a beta-type Ti-29%Nb-13%Ta-5%Zr alloy, developed for biomedical application, and their relation with the microstructure are investigated. The cold-rolled specimen is subjected to a tensile test at high temperatures ranging from 700 to 800°C under a constant cross-head speed ranging from 1×10-4 to 1×10-2s-1. The elongations tested at different temperatures are compared with that of Ti-15%V-3%Cr-3%Sn-3%Al, a typical beta titanium alloy. The deformation mechanism is characterized from the parameter of the strain rate sensitivity. The microstructures before and after the tensile test are observed with optical microscope and the correspondent grain sizes are measured. The grain growth during the deformation is also described.
