| Abstract: | Fusion welds in titanium alloys were characterized by coarse,column-shaped beta grains in the fusion zone. Poor mechanical properties and corrosion resistance in this zone have been attributed to a large beta grains size. This apparent beta grain size effect led to numerous attempts to better describe and control the welding solidification process. The results in this field were reviewed in this paper,and our study on Ti-6Al-4V alloy electron beam scanning welding was also described- |
