| Abstract: | The electron beam welding （EBW） properties of 7715D high temperature titanium alloy was investigated in this paper. The results of experimental works showed that the welded joint is smooth and has a tensile strength of joint of 983 MPa. It was found, however that the fracture is located in the heat affecting zone （HAZ）. The microstructure of the welded joint and HAZ is the typcial basket-waved grain. The base metal has a bimodel mierostructure consisted by α and β phases. |
