| 英文摘要 | The strengths of near (3 titanium alloy thick plate joints are usually reduced after fusion welding since only a small amount of alpha phase precipitates during cooling. In this study, vacuum electron beam welding (VEBW) with a 1-mm-thick Ti-6Al-4V (Ti-64) interlayer using novel sawtooth scanning (SS) pattern was designed to regulate the morphology and proportion of alpha phase in 30-mm-thick near (3 titanium alloy Ti-5Al-5Mo-5V-1Cr-1Fe, which largely enhanced the joint properties. The SS-joint with Ti-64 interlayer enhanced the joint strength most, with the increase in the tensile strength from 849 MPa for the joint without interlayer addition to 991 MPa for the SSjoint, which could usually reach similar strengths to the annealing treatment joints as reported. The improved strength was mainly attributed to largely increased proportion of acicular alpha phase for the SS-FZ with Ti-64 interlayer. The fracture location of the SS-joint with Ti-64 interlayer was in the heat affected zone (HAZ). Furthermore, the impact energy of HAZ in SS-joint was slightly higher than that of HAZ without interlayer addition, even superior to that of base material. This study provides a new economy and high efficiency welding method to improve the mechanical properties of near (3 titanium alloy thick plates. |
