: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......

Selective caser melting (SLM) is an AM technology that uses a laser beam with high... speed. The melting mode of SLM process (conduction mode and keyhole mode), which is the same as the laser welding, changed with the variation of laser power and scanning speed. The calculation method had......
