:Electron beam welding(EBW) has been widely used in the manufacture of titanium alloy welded blisk for aircraft engines. Based on fatigue crack growth tests on titanium alloy electron beam welding(EBW) joints, mechanism of fracture was investigated under scanning electron microscope(SEM). The results show that fatigue crack growth rate increases......
